My little brother is a freshman at IU. He went through fall rush without a bid and is now going through second semester rush. He has been invited back to 2 popular houses he is interested in this month. His friend received a bid from one but still no bid for him. The frat still has about a dozen to give out. He had no connection there i.e. older brother etc. but is a smart, fun good looking kid who enjoys sports and to party a little. I'm trying to help him but can't quite figure out what is going on. He has had a girlfriend he met early in the year. Do the frat's prefer guys who are unattached? Any ideas of what his situation may be?
