Anyone but me curious as to the "kid's" age? If he's young, you're right----he shouldn't be talking to strangers and I doubt he knows what a grimace is. If he's a young adult/adult---what's the big deal? He should know by now that not everybody likes everybody else and there will be meanies in this world who don't worship his daddy like he does.
This really may be the dopiest thread in a while.....
