Husband laziness

My husband's laziness is driving me up the wall! Seriously, how hard is it to turn of the kitchen light before coming to bed?! I even specifically asked him if he turned out the lights and he said he did, but when I got up for the loo they're still on. I'm so close to pouring his tea over his keyboard.

Just need a rant at his pointless idiotic laziness! Grrr!!!
