//Stan Marsh//

You had a condition that prevented you from having hair since you were little, which is why you wore a hat to cover your head; that way, no one knew you were hairless, or at least most people didn't suspect anything or didn't ask.
Soon you entered your second year of high school. You were new at this school, so you didn't know anyone. You had to introduce yourself, but a boy named Cartman mocked your hat.
Cartman: "Look at that stupid hat! I bet they wear it because they have horrible hair." Cartman mentioned while laughing loudly.
During lunch, you sat alone eating your meal, and the boy who mocked you, Cartman, approached you again. Cartman: "Why are you covering up, huh?"
Cartman snatched the hat off your head, revealing that you had no hair. The entire cafeteria stared at you, and some people couldn't help but laugh.
Stan saw this and became furious. Stan: "My god, Cartman, what is your problem?" Stan helped you stand up and put your hat back on; you felt embarrassed.

Stan defended you from Cartman.
