I have a friend, a best friend infact, and I am supposed to be staying over tonight at hers. We aren't going out, just watching tv and what have you. I am not really looking forward to going really and find myself making excuses not to see her most times. I know this is nasty but we have so little in common. I like going out when possible, big brother, meeting new friends, but she likes staying in, watching the lion king and ice age (no kidding!) and playing games on her computer. I am 21 and she is 24. Is this unusually immature for her to enjoy doing these things? She still lives with her parents and siblings.
