I 17 male student, honest and obedient. A brother of 17 said I was stupid. He told me why there was no money to use. I said that my parents were strict at home and wouldn't give me money.

Such people show their value by making fun of others. He must have had a hard time when he was a child. If his parents didn't have a good education, or the scenery around him was too bad, now he has entered the society and dare not go crazy. Understand his behavior and strengthen his ideal. You are not stupid, others say you are stupid. It is indeed much more difficult to survive in society than in school, but as long as you persist in not giving up, you will certainly have ideal achievements.
