I have one younger brother. Doesn't bother me or purposely do anything to annoy me in anyway...ever. We've never been in any fights, arguments, etc. And we always get along. I have no complaints.
EDIT: Don't judge Lightning on her post. I can back her up. I've only seen him once (Okay, I've seen him a couple of times. But I've actually "done" stuff with him once). He enjoys poking and trying to scare me, more than Erica does (Or "did." She hasn't done so recently). Erica at least stops after a couple of minutes when she realized that I wouldn?t react as easily, but him. Non-stop for hours on end. @_@ Forgive me Erica, I don't mean to sound rude, but you were there... you know he was like that. Actually...I'm okay with it. It was making someone related to you happy, so I'm good.
