You probably think I'm rude when I sneak away from the table, taking a few plates to the kitchen, trying and failing to go unnoticed. You probably think I won't let you help because I'm too uptight about the way things are done. (You would have been right about that 10 years ago, but I've recovered, and will happily let other people clean these days.) Worst of all, it might seem like I want the party to end, and for you to go home.
But none of that would be true. I don't want you to help with the dishes, but it has nothing to do with any of that.
