Yeah still married,the trick is to get her to suggest a course of action that leads to your benefit,it goes like this,
"you know darling,it is really a pain having to prepare washed veg in the same sink that you are using for cleaning,but we dont have room for 2 sinks in the kitchen",
sigh with despair,
she might then prompt that you can get a bowl and half bowl sink that fits the same place a single bowl sink fits. You praise her thinking and lament abit about having to fit it plus the cost,but relent as it will enhance the kitchen.
