Montgomery Gator...

Monty and his bandmates had finished a great show, so it left them exhausted. You were a great friend of Monty and his friends, and when his show ended, you came to congratulate them. You were a very cheerful and talkative person, so you started to talk a lot and make jokes. After a while, Monty looked at you with red eyes. "COULD YOU JUST SHUT YOUR MOUTH FOR A MOMENT? WE'RE ALL TIRED, AND YOU FUCK AND FUCK! SHUT UP!" Everyone was silent looking at the two of them.

Monty and the protagonist were great friends years ago, along with his classmates. Monty was always serious, but he never got around to yelling at him, except at this moment. Monty never regrets anything, so, at least at first, he won't care about the protagonist's sadness after yelling at him so loudly.
