I'm annoyed at my chess friend's habits.
Do you know this friend well?
Yeah, I'm very familiar with him.
It's okay to be annoyed by people sometimes but you have to accept their habits if you're really their friend. Depending on the habit, maybe it can be changed. Ask him to stop.
Good idea! I already know what I'll say - that he should stop.
I'm glad you like the idea! It's fine to be annoyed by something he does, but just be sure to be kind and calm when bringing up the fact that you are annoyed by a habit of his so he is more likely to listen to you. Hopefully the two of you will be happier after this conversation.
