Tonight, I was working with someone who annoys me. It's someone that I don't know particularly well. Some of it may just be that new job stuff -- I'm sure I was a pain in the butt before I really got the hang of things. But there's also something about the way this person interacts with people ... I dunno, it just rubs me the wrong way, I suppose.
So here's the thing: I'm sitting there tonight, and it clicks inside my head: I don't have to like this person. I can do my job, and complain to the manager when they're not doing their job, but it's perfectly OK for me to decide that nope, I don't like them.
It may not sound like a big deal to anyone else, but this is kind of news to me.
