Changing robes are dumb. Every now and then you drop your towel and some nuns see your church bells clangin' in the breeze, total win.
When I was a kid I was changing out of wetsuit one day on the coast highway. I got my wetsuit down around my ankles and one of the older guys yanked the towel off of me and pushed me out to the divider. Busy day. So there I am on the divider with my wetsuit down around my ankles and an endless stream of cars in either direction.
Instead of opting for the coverup, which would have fueled my torturers further, I stood out there and thrust my hips forward and waved to the oncoming cars. It took a few minutes for traffic to clear enough so I could leisurely pull up the wetsuit and stroll back across the highway to applause.
Sometimes you just have to embrace the situation.
