I've been around a lot--been there, done that, seen it all.
Except for my chance encounter today. That was new.
I walked out of my hotel (which is in a residential neighborhood) and almost ran into a mother and her young daughter. She was loudly addressing the child, standing over the squatting kid, holding the little girl's hands above her head.
I was at first confused and had no idea what was going on until I looked down to the sidewalk. And there, a little memento. The kiddie had pooped on the sidewalk.
Now, I don't much like it when I see a dog do that (doo-doo?). But a kid? Yuck!
A Mexican would call that behavior "mal educado" (badly educated). Or, translated into English, "you can't fix stupid."
