what is up with this chick?

Hah. The same thing has happened with me but I'm the girl.
I'm not sure about your situation since you weren't too specific, but this is what's going on with me.
So I'm sort of friends with my mom's friend's son. He's the same age as me. Sometimes I'll play around with him, no, not mentally, I mean as in physical games...That sounds even wors, but I mean just as buddies. You know?
Sometimes I can't stand him, though. I think it's mainly me because I just like him as a friend, but I get weird vibes from him. He doesn't do much but sometimes he'll just start touching me (not sexually) or carrying me around and it just annoys the fuck out of me.
I'm someone who doesn't like to be touched unless by someone I am intimate with, I've made this clear to him, yet he just won't back off.
I know it sounds like I hate him, but I don't. I just need my space. He doesn't get that I'll go to him. Just the other day I got all comfy on the couch and he just grabs my legs and puts them on his lap. I literally snatched my legs back and went, "Stop, seriously."
I know I sound like a fickle bitch
