Re worried senior's comment about buying into the package, I always say that something every chapter needs in rush, more than a good skit or cool house, is someone with an incredibly well-tuned bullsh** detector. Some people should be theater majors and don't even know it.
Also what is "moral" and what is not depends on the campus....some places, if you've slept with one guy, you're a whore because you're not a virgin. I don't want to get into a big moral discussion so I'll just say this: look at the girl in your chapter who is perpetual sunshine and never has anything bad to say about anyone. If she can't summon up anything nice to say about a rushee, THINK TWICE. One "no comment" from her is probably more telling than any of the stories anyone has heard!
