Peeing outside is more fun though. I do that a lot still. Less than I used to.
I was walking with a friend one evening. Just sort of a slow amble, listening to her prattle. And so I step behind a bush real quick and start letting loose. She didn't notice I'd peeled off until she was about 10 feet up, and she turns around in mid sentence, "Where did you... wait. You're not doing what I think you're doing, are you?" And starts to giggle.
It did not occur to me until exactly that moment that this might be not the most appropriate behavior for a grown man to indulge in.
