Ah now Catnapper that is why I go to the movies, because it is the only place I can sit still (sort of) and I won't leave in the middle of a movie, unless it is really bad, as I alway's hope something good might happen, now if it is a video at home, unless it is amazing, I am up and down like a yoe-yoe, always finding things to do, or that need doing, my husband is alway's complaining I never sit still, so I guess I must share your problem adult ADD lol, funny I can manage to sit behind a computer for
lengths of time though, but even then I have to get up and down. so you see you are not alone.
