They think they're better than everyone else. Yes they are involved on campus, have a nice house and could get any guy they want, but at the end of the day they have a bad sisterhood hood. Everyone looks alike and acts alike.
I went to their open house for spring recruitment during the Spring 2015. The girl I was with looked like she could give two cares less of what I was talking about. It was like pulling teeth trying to ask about TriDelta and their sisterhood, philanthropy. Fake and rude. All they have going for them is the house.
My roommate was in tri delt and I ALWAYS heard her talking bad about her sisters. The girls are pretty and have a lot of money but many are very superficial and materialistic. Definitely not a good sisterhood and would not be where I would choose to be.
