wait, don't I know you from somewhere?

My college reunion was a bit of a bust - I had fun, but the people from my class who turned up were James, who I work with, and Sheila, who I visit several times a year. Oh, and there was a pretty incessant parade of people either noting that I was "Donal's brother", and/or asking how he was in lieu of actually having a conversation with me. Bah. Still, as I say, I had fun.
