In good 'ol Texas we can still give it to our own kids. Supposedly the law allows kids to be served if they are out with their parents, but most people don't try it (at least that I've heard of). It's just not in vogue, you know.
As I explained it to my children, I'd rather if you're going to drink you do it at my house so I know you're not out driving drunk nor choking on your own vomit somewhere. After worshiping at the porcelain throne once each, mine seem to have given up the idea that it's cool. Once that was out of the way we were able to discuss responsible and social drinking in moderation. Both seem to have taken their experience and discussion to heart. On occasion we'll have crawfish and beer they might each indulge in one or two, but that's about it. I don't keep the liquor cabinet locked and we've never had a problem with it disappearing.
Our government seems to think we need babysitting in just about every aspect of our lives. It's too bad, really, because half of the problem is not being able to learn in a safe way at an age where the message will stick so we don't have the problems later on when we can actually do more harm (in a car, bar, etc).
