Probably go and watch a local club: AFC Wimbledon or Tooting (if at home). If they're away, then might watch some egg-chasing or might just lounge around.
Might watch Tooting & Mitcham or Fulham (if time allows, 'coz after that, off to Brighton to see Eddie Izzard), then back up afterwards to get to game tomorrow more quickly.
Going Xmas shopping. Which means I don't have to go the following Sat. so I could have gone to the Port Vale game. Only it's Friday night and I've got an Xmas do I can't get out of!
