Some girls are nice, some girls are not. It's the same with boys though. It depens on the personality so much.
Girls are nice for talking, girly stuff (like "omg can I borrow your lipstick it's so pretty!"), for discussing about people you dislike, and being silly. Even though I hang out with boys a lot, I need my daily amount of girl company. So yes, I like girls. I also like being a girl.
