Petunia is Lily's older sister, and both are the daughters of the Muggle Evans
However, the appearance, mind, and magical talents of the two people are completely different
In Muggle families, Lily could show her magical talents and blossom beautiful flowers in her hands
Petunia, on the other hand, would not do anything but watch her sister's magic in a hurry
After learning of Lily's magic, the Evans were amazed and proud
They always praise Lily's abilities, which makes Petunia feel that she has been snubbed and begins to hate Lily
Later, Lily met Severus Snape, who had the same magical talent as him
The two children discuss magic together every day, and they often have fun
But Penny hated Snape so much that from the first time they met, Penny kept belittling Snape's financial situation and mocking him as a poor boy
Plus once, Snape failed to control his magic and accidentally let a branch hit Petunia's shoulder
Petunia hated Snape even more
When she saw that Lily had received the letter of admission to Hogwarts, Petunia was both envious and jealous
She secretly wrote to Dumbledore, asking if she could go to Hogwarts like her sister
But Dumbledore politely rejected Penny, and the shameful fact that he voluntarily enrolled in school but was rejected was known to Lily and Snape
Enraged, Petunia begins to dislike Lily and Snape even more, calling the two of them "freaks" and saying Hogwarts is "a school dedicated to monsters."
Petunia envied that Lily could have the pampering and praise of her parents
She envied Snape's adolescent love for Lily
She envied that Lily could effortlessly get praise from everyone around her
In Penny's mind, the sister had everything, and she had nothing
She was jealous of Lily, and she hated Lily, and she even hated her parents, who were proud that Lily was a wizard
Still, on the day Lily went to Hogwarts to enroll, Penny went to the nine-and-three-quarters platform to bid Lily farewell
Seeing Lily's distant figure, Penny's heart was full of mixed feelings
Growing up, Petunia wanted to stay as far away from the wizarding world as possible, and she tried to live like a normal Muggle
In her mediocre work, she met Vernon Dursley, an ordinary man who was very satisfied with the ordinary world
The two men fell in love with each other and soon decided to get married
Petunia was worried that Vernon would turn her back on herself because she had a freak sister
She thought about it and finally decided to tell Vernon about it
Unexpectedly, Although Vernon was a little surprised, he did not dislike Penny because of it
Instead, he assured Petunia that he would treat petunia well
At this point, Penny was completely at ease
When Petunia takes Vernon to meet Lily and James, Vernon tries to show his charm in front of James
While he tried his best to show off the car he owned, Jaime told Vernon that he was traveling with a broom
The conversation between the two people became more and more outrageous, and the communication was completely off the same channel
Vernon did not know that Jaime was also a wizard, and thought that Jaime was teasing him, and the two families could only break up
At Vernon and Penny's wedding, Petunia fears that Lily will steal the limelight and even refuses to let Lily be her bridesmaid
After marriage, Petunia and Vernon had a dull life and gave birth to a son, Dudley
It's just that petunia and Lily have less and less contact, and even at Lily and James's wedding, Neither Petunia nor Vernon attended
After Harry was born, Lily wrote to Petunia, telling her she had a son
But Petunia just glanced at the letter and threw it away
Petunia had thought that she had thus forever escaped Lily's shadow, from the shadow of the wizarding world
Unexpectedly, it all changed that morning
When Penny got up early in the morning and opened the door, she saw the baby at the door and a letter that Dumbledore had left for her
The letter mentions that Lily and Jaime have been killed and died, and that Voldemort, the murderer of both of them, has disappeared without a trace
Dumbledore tells Petunia that she used her life to guard her son Harry before Lily died, inspiring an ancient guardian spell
So, as long as Harry stayed where he was related by blood, he could be spared persecution
Before Harry's arrival, Penny, though still very disgusted with wizards like Lily, rarely talked to anyone about herself and such a sister
But deep down, she always remembered that she had a sister, and she had loved this sister deeply
However, after learning that Lily is a wizard and that she is just an ordinary person, she is blinded by jealousy
Petunia had also hoped that she could have magic like Lily and enter Hogwarts to study
What really made her despair was not wizards and magic, but that she herself was not a wizard, no magic
Therefore, after reading the letter that Dumbledore left for her and learning of her sister's death, she had no choice but to be reluctant
She could only take the baby in front of her home and raise him
In Harry's childhood memories, Petunia had hardly ever had a good look on him
Harry lived in a storage room under the stairs, wearing only clothes that Dudley didn't want, and making breakfast for the family every day
Petunia told Harry that his parents had died in a car accident and that the scar on his forehead was the result of that car accident
Out of fear, Petunia and Vernon wouldn't allow Harry to ask any questions about his parents
It wasn't that they hadn't thought about Harry's future, they just didn't want Harry to follow Lily's path
So, seeing that Harry had received an admission letter from Hogwarts like his sister Lily, Petunia and Vernon did everything in their power to stop Harry
They even moved their families to the island, because in the Muggle world, they believed that wizards could not cross the ocean
But this still could not stop Hagrid, and on Harry's birthday, Hagrid found Harry with a cake and invited him to Hogwarts
Facing the wizard giant in front of her, the anger suppressed in Penny's heart once again erupted
Under Penny's furious accusations, Harry learns his true origins and knows who his parents really are
Forced to do so, Petunia had no choice but to allow Harry to go to Hogwarts
During the years of Harry's schooling, Penny reluctantly allowed Harry to stay at home for the sake of blood protection
Until Dudley was attacked by Dementors in the Muggle world, Harry was forced to use magic to save Dudley
Petunia told Vernon that she actually knew a little about the wizarding world
Petunia said that many years ago, "That Terrible Boy" (Snape) had told Lily about Azkaban
Vernon, who learned the truth, would no longer allow Harry to live in his home, and Petunia agreed
But when Penny receives a yelling letter from Dumbledore, "Remember My Last," she changes her mind in an instant
Petunia insisted that Harry remain at home despite Vernon's objections
As time went on, Lily's magical protection grew weaker, and there was no point in Harry staying at Penny's house
To keep Penny's family safe, the members of the Order of the Phoenix decided to take them off Privet Road and take them to a safer place
Before leaving, Dudley told Harry sincerely for the first time: I don't think you're a waste
And Penny, she looked back at Harry, and for a moment Harry felt as if Petunia was going to say something
She looked at Harry with a strange look, trying to say something but never saying it
Later, the family of three completely left Privet Road
Rowling said that Petunia at that time actually wanted to wish Harry good luck, and she did not actually want Harry to die
However, after so many years of pretending, Petunia's heart had already hardened, and she could no longer say such soft words
