Do you remember when you were a kid, and you just finished doing something spectacularly stupid, and then your mom would say, "You just wait, Buster. Some day you'll have children of your own, and then you'll get yours..."
As with most things, my mother was right. My son spent the better part of his childhood doing heroic duty to her memory, picking up and channeling every one of my childhood sins so that they could wash back over me in a giant dose of Kiddie Karma. Now that my son is grown and married, I've decided that I’m going to raise the ante.
You see, as parents it was our job to teach our kids to say, "Thank you" and to keep their pants pulled up when we had company. We had to convince them that it is generally a good idea to flush the toilet. It was our responsibility to mold them into future doctors, lawyers, astronauts, politicians, armed robbers, or televangelists.
A grandpa is free to be nothing more than a kindly old coot with an endless lap and a bottomless wallet.
