Ovens

When I was a kid my mother would, after cooking a big meal, insist on leaving the oven door open, "to let the oven cool down." Which drove me crazy, since if you were within 10 feet - say, for intance, to get a drink from the fridge - it'd be like walking by a furnace blast. I'd be like wtf; you're not using it again til tomorrow, won't it fucking cool down by then? And who cares anyway - IT'S A FUCKING OVEN!!!!!! Shut the door!! Drove me bananas. I find it hard to believe that anybody found themselves throughout the house thinking "hmm...I sure hope that oven has cooled down...."
