If you're of "the weaker sex" you either sleep or doodle because you don't get the luxury of doing anything else to pass the time at meat-ings. I use the excuse that my back hurts (which it usually does after sitting too long) and get up as much as possible.
Since I usually ride with, or take, my Mom to ass-em-bleeds and con-ventions screwing off is pretty hard to do. However when I was a kid my Mom always proudly let me "volunteer", so I would "help" with things like emergency clean up during sessions because the cleaning department was goof-off central.
The BEST EVER was one year when my Mom and I went to different con-ventions; I listened to my mp3 player, goofed off, got up (a lot), sat where I could sleep easily, parked strategically for an easy escape and got my shight together early so I could be outta there before the last echo of amen could bounce back.
This year we may have to go separate again and I'm hoping we do!
