The whole thing with them not participating in the games and stuff really ticked me off. The whole crack about making it feel like they were 5 years old again really got to me. Like the one girl said on the first episode (I think it was Becca) that if the pledges didn't want them to be there, they wouldn't have any problem shipping them out. Maybe they should bring up that option to the girls in the house that arn't following the rules.
Oh, and them trying to get Jessica to follow them in breaking the rules... talk about acting like you're 5 again...
Many other things made me mad, but I'm too worn out from the show to gripe about the rest of them...
