So, on one trip to Rome, I started going crazy and began jogging up and down the aisles (yes, I know one couldn't do that post 9/11). The flight attendants were cool with it (my husband was a two-million miler at that time - they aren't gonna mess with him). While jogging down the aisle, I heard my name called, and someone said, "Hey, is that you?" It was a high school friend that I hadn't seen since, well, high school. I was so embarrassed. I've stopped jogging on international flights. Now I do needlepoint for cushions at our church. It is very relaxing.
