Looks like I'm joining Ollu & Zeocon's Leaky Home Clvb, was woken up about half midnight by the sound of water outside my window and thought 'that doesn't sound like rain', discovered it was coming from the flat above and also that water was trickling down the top right corner of both my bedroom and living room windows. Found the guy who lives there on the phone to the fire brigade, told me that his flat was flooded and he didn't know how to turn his water off... Went up there, loads of water coming from the boiler, worked out which was the main water supply and switched it off, eventually a guy from fire brigade turned up so I left them to it (was just getting in the way by that point). By the time I'd cleaned up the water had pretty much stopped, no real damage apart from stains and some flaked-off paint, really lucky it happened while the guy was at home, got paranoid about it getting near electrical stuff. Didn't get much sleep though so feel like crap. Listening to Yo La Tengo.
