When I'm sad, I look up at the sky and that helps me to feel sad. I also don't know why. Looking up at the clouds floating in the blue sky, they are free to fly in the sky, when they are bored and want to return to the mother country, they just need to make rain. As for children like us, wherever we go or do everything is under the control of our parents. I was even detained when I did nothing wrong but got blamed. It is the distrust of parents, they want to control but they don't know that excessive control creates a hatred for them, wants to be independent and does not trust them. I wanted to say more, but now my hands are tired. Come on, bye bye~~
