when they go on about how lovely and warm their kitchens are at this time of year. FFS, if I left the electric oven on 24/7 in my kitchen it would be lovely and warm, but would people be saying "ooh have you been to Cleggy's house, his kitchen's really cosy"? No. They'd be saying "have you heard about that idiot cleggy, he leaves his oven on all night to heat his kitchen."
It's the same thing. Except that my fuels bills would probably still be smaller. Here endeth the rant.
