I believe that the writer of those famous words, eg "out of the mouths of babes", was a parent who had been on the receiving end of a child's wisdom more than once.
AND, if you ever want to be embarassed, trust your child to drop you in it as a matter of course. Some family events I would have preferred did not leave the house, starred at my kid's school show and tell, to my horror.
I am now getting my revenge, via their children, doing unto their parents, (my kids) what they did to me.
I always knew there was a God.....
God bless
