So I was just talking to erin who was saying that i shouldn't complain about being the only single person in the room since, the expected number of days i'll kiss a girl this semester may be higher for me than for David since they only see each other on visits. This segued into some very amusing stories about her blocking group and my saying that i wasn't ever the only single person in our room, and that in turn reminded me that there was one day during college when all 4 of us were with girls we were dating. Erin said "which day?" and we concluded it was: Saturday, 7 April, 2001.
