Number One: It's not the child's fault he has crappy parents. Number Two: You all that judge have no idea where I might becoming from. Everyone thinks their child, grand child is the best. cutest, smartest, most special and unique person ever to grace the planet. EVERYONE thinks this, so kind of proves it's not true! Number Three: I have no problem with a parent trying to teach their children how to behave in a nice restaurant. But how about not doing it during prime adult time? Do lunch!
BTW: I do notice a well behaved child and when I can compliment the parents. Planes? Kids cry on planes! Church? Kids get bored in church. I deal with that. Even offer the parent a sympathetic look. but when I go out to a nice restaurant I want to enjoy my meal and the ambiance! Sue me!
This is important, and I try to remember to do it, too.
Something like "Your children are very well-behaved. Such ladies and gentlemen!"
First off, everyone likes to be complimented on their children's character traits, so it's just a nice thing to do. Maybe they've had a rough day, and a kind word is a blessing.
But, secondly, the children also hear it. Positive reinforcement. It's a good thing!
