Don't put your dirty dishes in the sink. Yes, you read that right, I said "don't". Unless you are one of those awesome people who does the dishes immediately after every meal, dirty dishes in the sink are just going to be in the way. When the sink is full of dishes, you can't wash just one cereal bowl so you can eat breakfast. You can't get to the garbage disposal, so apple peels just lay around getting moldy, stinking, and attracting flies. You can't get the Brita under the tap to refill it, so you leave it empty in the fridge. Dishes that were only slightly dirty end up getting gross and sludgey from sitting inside pots that were left to soak. Metal things end up leaving rust circles on the bottom of the sink.
So please, at least when you come to visit me, don't put your dirty dishes in the sink. Stack them on the counter beside the sink; I'll get to them eventually.
