I don't want to depress you but experience says your dish will stay if she lets you, and if she doesen't there won't be a goverment or army that will prevent it. It may not be fast and you might put up resistance at first, but after a few years she will nag the dish out. The only dish you will have inside the house is the ugly flower decorated porcelain plate your mother in law brought her from her holiday. The only dishes you will be turning are the once you are drying after washing them.
