in the very beginning charla did join in on some of the group activities but eventually she realized they weren't her kind of people. if you notice nearly everyone from the beginning was from arizona and sometimes people from the same area have more in common. she's from minnesota and i think dave said she's never really left. if you ever met someone from minnesota that's always lived there they sort of have a different vibe from people on the west coast. and just cuz your on vacation doesn't mean you have scream, get drunk, and hump every person you meet. and that's all everyone else did. i remember one time she finally got fed up she said all the guys did was talk about boobs. she did enjoy the outing they had when they were traveling and stuff some people like to go on vacation and enjoy the sceneryu and have good, clean fun and i can respect that. and lastly they called her boring when she didn't want to stay up all night every night. amy complained that she was going to bed at 1 am and said she wished melanie stayed instead of her. maybe not in amy's world but 1 am is not early.
