I don't know when I didn't like watching cartoons, I don't know when I didn't like to play with my friends, I don't know when I became taciturn, I don't know when I liked to be alone

I don't know when I didn't like watching cartoons

I don't know when I didn't like playing with my friends

I don't know when I became silent

I don't know when I like to be alone

I don't know when I liked the quiet

I don't know when the irritable character has converged

I don't know when I didn't like to talk about dreams and hopes

I don't know when I didn't like spending lavishly

I don't know when I looked down on a lot of things

I don't know when I didn't like to talk about other people's things

……

I don't know, I don't know, there are so many people who don't know when.

Perhaps, people see things differently at every age.
