One of my closest friends was the house director for another sorority on campus and those women loved her. She would do the usual duties of a house director but she'd also go out of her way and make them little gift baskets for the holidays, finals, stuff like that. She'd also look the other way about certain things as well.
My friend should have been a sorority girl and I'm still hoping that she'll be AIed into that organization because she deserves it
I guess it's a balance between being a friend and being a parent, knowing when to look the other way and when not to.
