33, co-sign to you!! As for the woman's age, etc., I can't imagine an over 30 year old woman believing she will mesh with a group of 18-22 year olds. I go to chapters sometimes to do visits and what not, and at 30, I can honestly say I'd NEVER be able to be a collegiate member again! Too much drama
Alum initiation is an option after she's out of school, and if your chapter likes her a lot, sponsor her when she's graduated. Otherwise, go with how the chapter votes and let the chips fall where they may!
