Dear...

Why do you act this way? You came home from exams, and called your mother stupid because she told you to stop yelling at your sister. You said that she "wasn't even there", oblivious to the fact that mom was two feet away from the whole ordeal. You cannot go one day without starting a fight. Just stop it. We're all sick of your crappy attitude. Mom bends over backwards for you, helps you, stays up late for you, and this is how you repay her. You're a horrible son and you don't deserve the wonderful mother you have.

Sincerely,
your youngest sibling
