Embarassing?

Have your kids ever embarassed you? Mine have, probably a million times each by now. Lately, we have been noticing our 4 year old has decided it's not worth the trip indoors to pee. He is a boy, so it's easy for him to take care of that sort of business in other places than a bathroom; the back yard, the driveway, etc. Will has seen it more than I have. I have only witnessed it twice. The other evening, we were taking our walk and he decided he needed to go. Right there on the track we were rounding. Nevermind, the small group of kids on the other side of the field for soccer practice. We were a ways behind him, so we were not able to stop him before he got started. Maybe nobody saw it- but somehow, I would doubt that. We scolded him, and he just informed us that he needed to go. That was it as far as he was concerned. Oh my!
Fast Forward--
Today, we were talking through the Home Depot and there was something spilled on the floor. The kids excitedly pointed out the spot- I hope it was water- where someone had peed. Will said something about it looking like Calvin had been there. I replied with something like, don't give him any ideas. And Calvin jumped in with; "I didn't pee here, yet." Oh my--yet?
