just to aggrivate

Why do people ask you "What do YOU WANT me to do" when they know good and well they are going to do what they want to do anyway?! Even when its something you specifically said "no" to in the first place. (& it wasn't an opinion it was a "this or that" question) SOOOO frustrating. Really, its completely silly, but none the less, don't ask me if you don't care what I have to say.
