My old friend, Manfred, lost the lower portion of each leg in a motorcycle vs train accident when he was in his teens. That restricted his mobility but not his sociability. When we attended psychology conventions, he used to reserve a room near the entrance of the hotel and buy enough wine to share with any psychologist who wandered in. Then there was the time Wes Coons (a very respected senior psychologist) and I plopped ourselves down in the hallway leading to the main ballroom during one of the APA conventions and greeted all who stopped by. I miss the old sociability, but that is probably just because I am getting older. I am sure that the young people are just as party-prone as we were.
