Why is it my kids can be engrossed in a puzzle, some made up game, coloring, tv, whatever, but... the minute I step food in the bathroom and lock the door there's 2 of them outside the door? Knocking, poking fingers, toes and toys under the door. Is this a fun game? The second I come out of the bathroom however, they are back to being engaged in whatever had their attention beforehand. Sigh.
