Dislike someone?

When I was in the middle school, I was always surprised to hear that someone disliked some others. Might be because of I was too childlike, or ... I just simply like anyone around me, I think.

Things changed the time came to my university life. Might be because there were more people I needed to face with, might be because I grew up to more mature, anyway, there were a couple of people that I didn't really like, even one or two I hated to see or being together with.

Then, it came to today. There are always someone around you you found a bit annoying, are there? How about you, my dear readers?
