I have a younger sister, but I am actually shorter than her. My classmates laughed at me. I am very upset and don't want to be laughed at by everyone. What should I do?

It's okay. Go your own way and let others talk.

You also have advantages that your sister doesn't have. Believe in yourself.

In fact, everyone has more or less troubles, and we can't block our way to happiness because of these nothingness. Really, think about your own advantages.

When classmates laugh at you, give more psychological hints. You are the best.

You can do it.
