Sitting in a room, talking with a guy sitting next to you. Another guy walks up and interrupts you and apparently oblivious to the fact that you and the guy were talking and just starts having a conversation with the guy you were talking to andnignores you.

Once every couple of years I run into a buffoon like that and I’ve yet to really find a satisfying way to approach it. Right now the best approach I’ve found is to just roll with it, but there has got to be a more satisfying way to deal with rude in-steppers.
