There is nothing good about school except for the possibility of making a few true friends. The body changes, parents become stricter and brainwash more, going to school every day is like going to work, doing homework, hating the world around you, and thinking of yourself as the only smart person, suffering from envy towards classmates with better phones or computers - yes, it's a heavy burden.
It's understandable that adults, who have a boss constantly breathing down their necks, might sometimes sigh about the "good old days" when they were fed and clothed, and when they only studied at school for half a day, but that's all nonsense. Would you want to go back to being one and a half years old, with soiled diapers and unlimited parental adoration?
