One night, I was just about to do the dishes when I noticed that Mum had already washed the pan she cooked dinner in (chicken, egg, carrot, cabbage/lettuce on mee-hoon, if you must know). Our conversation went down something like this:
me: aw mum! did you wash the pan already?
mum: ya...
me: aw, you shouldn't have!
mum: well, you could do it again if you want to... I don't mind paying for the extra water
hahahahahahahaha oh, I just about died dead.
and that's my mother and your sister for you. at her finest.
