They hide the cups they use, so they can use them later... instead of getting a clean cup. M found B's cup in the sink, and pulled it out and used it.
They put open food containers in the fridge (my BIGGEST peeve).
The way M asks for things: "Would you be so kind as to come into the other room as I would like to show you something" (heirloom presentation time).
Saying every 10 minutes "we'll need some time to get ready if we should go somewhere", when we told them we aren't going anywhere, but they want to go somewhere, but they don't want to tell us that they want to go somewhere.
M asking me how my mother is doing, and in the middle of telling her, she breaks in to tell me a story about her grandfather that lasts for 45 minutes and has nothing to do with our current conversation.
I came into a room as hubby was explaining the glories of e-bay, and how they could take their stuff and sell it and make money to do fun things instead of wasting postage sending it to us. It didn't sink in.
