Last summer, I had a similar instance. She's about 70 years old. Not a child. I had the camcorder set up for birds. I happened to record her dog shitting near the corner fence post and the ensuing conversation when I saked her if she was going to clean it up as she was walking away. She was vicious, obnoxious, profane, and refused to admit it was her's to clean up. Worse than any child could be.

A half hour later, a large young gentleman confronted me and, essentially, wanted me to give him a reason he shouldn't beat the crap out of me for being nasty to his mother. I showed him the video.

Video. That is your only defense these days. Saved that large young gentleman an ass whoopin. >;-)
