OTW.....You are my new best friend!!
I do understand the notion of not wanting your loved ones to be unhappy and grieving with them, but then there is a time to 'pull yourself up by your boot straps'! After you pat your kid on the back you shouldn't say "What is wrong with my daughter?" Tell her about other organizations to belong to. Greek life is not everything. Believe it or not if someones wonderful, brilliant, super smart rhodes scholar daughter gets cut....the world keeps going.
I think I am like AlphaGamUGA's mom: Give words of encouragement then tell em' "Yeah, that's too bad....now move on"
