I'm going to tell my friend I don't care about a tv show and that I hate it more because of how much she talks about it
Why don't you like her talking about the TV show? Do you have a problem with the show?
Now that you mention it, yes there is. People must know that if they talk about it I'm not interested anymore.
I understand it's very annoying when your friend keeps talking about the show you don't like. You should let her know how much you hate the show, maybe she'll stop.
Thanks for the suggestion. I tried talking to her about it, but she didn't get it.
Well at least you tried to get your point across. If it becomes insufferable, you should try talking to her about a TV show you are interested in. That way you both have something to talk about and be engaged in.
