When I was drinking, it was well away from my son. He has no idea what is behind curtain number #1. Now, the chances of my wife being pissed off at me at some point and saying your dad is working out in the yard and too busy drinking, well, that is a possibility.
My wife doesn't drink, but her dad is 70 and puts a six pack (give or take) away every day. Her mom does not touch alcohol. Both of my in-laws parents, from what I've heard, I would consider them (they've passed) as alcoholics. My mother and father are not. My dad's father died of cirrhosis at 55. He was an alcoholic.
Try to chart that and make heads or tails.
But as far as my son goes, I will definitely have the talk with him. On the other hand, he lives in a very controlled environment with loving parents, positive reinforcement and guidance.
He will get the peer pressure lecture along with anything else that he can use as a tool for success.
I think that it goes without saying, that I'm thinking the same as you xNx.
