I don't think it's a conscious things that girls do! Girls are friends with other girls because they enjoy each others' company. There may be some shallow people who think it boosts their chances having an ugly friend to be compared to, but most will be just as eager for their friend to hook up with someone nice as for they themselves to. I would much rather have a friend with me who could hold an interesting and funny conversation with any guys we met, and would make us seem interesting and fun to be with, whether she is better or worse looking than me - whatever! Girls just wanna have fun!
not really. everyone has ugly friends, except for the super gorgeous snobby girls that refuse to hang out with ugly people. I'm sure compared to some of my friends, I'M the ugly friend, but compared to some other friends, THEY'RE the ugly friend. I choose my girls based on personality, how well we get along and what we have in common. it's insulting to be with them because I'll look better in comparison. sure there are some shallow girls who do that, but it's rare and most of us aren't like that. realistically shallow girls only want to hang out with beautiful girls so they can be the group of pretty girls. I actually have some friends like this who hate hanging out with ugly girls because they say the ugly ones bring the rest of us down.
