They think it's adorable. The kids run wild in restaurants, ruining everyone else's dinner ear-splitting shrieks. The parents just smile proudly when other diners glare at them. They are the same with their dogs, letting them crap in your yard, run off leash against the law, etc... "Aww! Isn't he cute?"
“..same with their dogs..”
Agree +1 on the kids part, +1000 on the dogs part.
