I have an issue with one of my oldest friends of like 10 years. I don't know what it is but for a little while now things are mostly good but sometimes he'll say something in a way that just irks me so much (and it's not even the content of what he's saying, it feels like it's down to his choice of words and the way he says it) and I have no idea what to do about it because it's completely unreasonable of me to feel that way and yet I still do. He's a great friend, very considerate but sometimes he'll say something and I'll just get that feeling again. It's very strange because I don't really feel this way about any of my other friends.
