I don't want to listen to my brothers shitty retellings that he insists are funny
What is it about his retellings that you find boring?
He bores me to death with stories that are repetitive. They are stupid.
He is just trying to be nice and share things with you. I know they are annoying, but try to be respectful.
What? It's his own fault for telling a boring story. I don't need to be sensitive to his feelings.
It can be really challenging to pretend to be interested in something you dislike, but your brother will appreciate your interest. Instead of thinking about his retellings, think about how excited he is to talk to you about something!
