I have a confession to make! My 2nd husband once pointed out to me that I would wait until he got up to walk out of the room, then I would start talking to him. Honestly, I thought it was more convenient for him, that this way I wasn't interrupting his reading or whatever. But he was on his way to doing something else, and felt that while he was in the room with me, that was my cue to talk. But that wasn't how I was raised - my family didn't want to be bothered by me while they were reading or watching TV.

On the other hand, is mammy doing chores that you could be helping her with? This could be her way of hinting (sorry, i'm old!)
