Just for contrast from the convivial violence of an NMA moshpit, I got a "help! we need a fourth for bridge" call on the train on the way back, so turned up to Relativity for a few hands before general consensus was that bridge is a game better played by awake people. (Opening bidding with a 6-5-2 hand containing 10 points was especially amusing).
Today my body decided it was time for a rest so lacking any reason not to, I slept until 3pm. It's been a long time since I slept in quite so late.
