4th Letter to Strange Friends:
Strange friend Ann, see the letter as it is.
This weekend, I want to know how you lived, who you met, what kind of scenery you visited, and what delicious food you ate. This city, another day in the hot sun, accompanied by the noise of knowledge, is not angry. In such weather, my mother and strange friends were worried. One phone call, one broken thought. I whispered in my mouth, and my heart was warm. Dinner was sauerkraut fish from the little restaurant downstairs. The master is good at craftsmanship, the fish fillets are very thin, fresh and tender. I eat very slowly, and I hope that in the near future, I will be able to change cups with you and talk about some idle past.
After the meal, I circled downstairs, the sun had already set, and there were some breezes blowing in the city after a hot day. Under the street lamp, there is a mother with her child blowing bubbles while cooling off, and due to the breeze, the colorful bubbles fly high and far. The child laughed and went to chase, almost bumped into me, I was afraid of hurting her, reached down to protect, the little guy staggered away. The child's laughter sounded very healing. Let me think back to my childhood self, when I was a child, I was not like the old city now, when I liked to climb trees and pick fruits, naughty like me, but also suffered a lot of parents.

Strange friends, if you have time, let's go back to our hometown together. Look at the magpies nesting in the treetops, see the corn growing very well in the fields, and the morning fog and sunset...
Good night.
