My mom was not Greek, but she was a Sigma Nu Lil Sis (or something like that). She doesn't really get the whole sorority thing, and a lot of times she playfully mocks the silly things that I have to do, like the chants or "secret stuff". But she supported me when I told her I was going to rush, she pays my dues, and she is completely thrilled at the fact that I am so happy. She sees that Phi Mu has made me so many friends and keeps me busy. She also likes that I do a lot of traditional college stuff, like going to basketball games, that I might not have done before. So while I can't say she completely understands, she is cheerfully clueless
