lower tolerance

I’m finding it harder and harder for me to communicate with those who incessantly talk about themselves.
It makes no sense to me how those people ask how I’ve been. It’s so blatantly written all over their faces that they want me to quickly finish what I’m saying just so they can start talking about their own. I mean, what the hell kind of conversation is that? Might as well as go talk to a wall.
It’s worse when they start humble bragging. And don’t even get me started on when their bragging is inconsistent. Which one is the lie? What can I believe? Actually, why can’t they just be upfront about their achievements…?
I always hold these things in because I’m pretty anti-conflict, but I feel something has to change. I don’t want to forever listen to people who hold conversations just for their sake.
