Ohhh my...many of you were very creative!
I would usually just write notes back and forth between friends that were sitting by me.....
Towards the end, I had back problems (no really I DID) and would get up and stand in the back of the hall to stretch & chat with other "sisters". It was an easy way to "people watch" too!
Or I'd pretend to be helping a mother with her child and go to the bathroom. We'd just talk the whole time or play with the baby.....
