my kids saw a tv show and the topic that night was a character who was an alcoholic they then put 2 and 2 together....
my kids dont seem to have any interest at all in drinking or smokeing and get mad if i mention starting back up again. I hope they stay that way.
I know some who had parents who where alcholics and as a result never drank themselves. But i know others who also ended up alcoholics. I dont know what the magical answer is but enjoy it as it is while you can etc..
