Margret flooded the kitchen last week. Turned the taps on, put the plug in the sink, and utterly forgot about it (because she'd come upstairs and we'd got involved in an unrelated argument). She goes back downstairs, opens the door and - whoosh - it's Sea World. The interesting thing about this is, if I'd flooded the kitchen, it would have been a bellowing, 'You've flooded the kitchen, you idiot!' and then she'd have done that thing where I curl up in a ball, trying to protect my head, and she kicks me repeatedly in the kidneys. As it was, however, there's a shout, I run downstairs and stand for a beat in the doorway - taking in the scene, waves lapping gently at my ankles - and she turns round and roars, 'Well, help me then - can't you see I've flooded the kitchen, you idiot?'

Margret's four-hundred-and-fifty-second most annoying habit is to stealthily turn off the central heating (then light the gas fire in the room she's in, natch). I'll suddenly notice that, sitting typing at the keyboard, I can see my own breath while from the bedroom one of the kids will call out, 'Papa, I can't feel my legs...' And I'll shiver down the stairs to find the central heating set to 'Summer/Hypothermia/Cryogenic Suspension,' and Margret in the living room watching the TV in a door frame warping furnace.
