I used to have long hair. I just had my hair cut short. My classmates call me mushroom head. They laughed at me. What should I do?

My friend, in the afterlife, first of all, you should live for yourself, not in other people's mouths. Be yourself, unique on earth! It's true! What others say is someone else's business, and many great men follow their own instructions no matter what others say! Remember, you are your own general!
