Honestly the teacher laughing was enough, literally no one is going to give a fuck after that.

People need to realize that they are not the main character, if you want something embarrassing you did to go away just don’t bring it up. People aren’t jotting down notes to bring up later, they have full lives of their own, no one in college has time to commit this to memory any more than a funny anecdote and they won’t bother to remember who did it.
