A classic example of getting your own back on a family member you've fell out with lol!

A ex sister in law phoned me up one day to ask me where my brother was living now so I told her we dont talk anymore so I dont know
so she sounded a bit upset with him for something or other and wanted to hurt him.
Not my type at all so I said if you really want to pee him off tell him you are dating me now and that will really do his head in LMAO!
