About 75% of my cousins, who were allowed to drink at home, are alcoholics today. My siblings and I, who never drank at home with our parents, are able to enjoy one drink and stop.
Sounds like you have really unfortunate genes in your family.
In MY family, there seems to be an "on the edge" gene. My mom flirted with being a little too free with her wine, realized it, and pulled back from it. My dad could be considered an alcoholic, and after literally running his wife's car into the side of her garage, chose to stop drinking for a good decade, but now, ages later, can and will have a beer at a social function, and he's FINE. He's not the nicest man in the world, but that didn't change when he didn't drink at all.
I went a little bit too far in my 20s, and pulled back. My brother didn't drink for absolute ages, once he started went a bit too far, and pulled back. It's actually pretty interesting.
And in MY family, it doesn't matter one little bit if your parents let you have alcohol. My first taste of beer was at 8 (Coors), from a family friend who was so close to us he might as well have been a second dad. I still have a soft spot for Coors on a hot hot summer day. My brother would have been allowed it, but he never WANTED to. He can *smell* wines and tell you about them; he actually had a job at an upscale wine shop for summers in college, and did REALLY well, despite never having actually TASTED the wines; his nose is THAT good. It wasn't allowed in my mom's or dad's houses (meaning, my mom and dad weren't *allowed* alcohol while at home...they married at 17/19 though).
In my very extended family, practices are very different from house to house, but the "pulled back" story repeats itself over and over. Didn't really matter what happened in the home! *except for in the really *messed up* homes...and even in those homes, you don't see EVERY child coming out the same way...
This. The first time I felt tipsy I was out to dinner with a family friend and the wine was served in big glasses, heh. It wasn't when I was randomly carousing around in college and got blindsided all of a sudden, it was like, oh, whoa, huh. That's how you learn your limits and what it feels like and what warning signals there are.
And that was such a SAFE place to learn that feeling. First time I felt super-tipsy was as a college student, surrounded by cheap beer in kegs, with a party cup in my hand that kept getting refilled.
Although wine was around in my home growing up, I hated wine. Turns out I like beer (even now, wine might sometimes taste relatively decent, but it gives me such bad heartburn it isn't worth it), so the wine didn't help, because I didn't drink it. Would have been a lot better to have a little beer at home, instead! Because I'd never felt that way before, and in the frat party surroundings I was in, stepping back from the feeling wasn't something that was easy to do.
No and it is illegal in Arizona to do so. Even for a parent to give to their own child.
I can't find that. Can you show a link? Only thing I can find gives me the law that's all about *establishments* and bartenders and whatnot.
It's DS12 I worry about.

He knows how to tap a keg (thanks to my BIL), make martinis (thanks to my BFF's mother in law) and can tend a bar like nobodies business (thanks to my good friends who have the bar). Everybody we know jokes that he is going to be the president of his fraternity in college. I believe it. The kid is a hoot- and a natural "people person".
Sounds like my husband. He could make his dad a perfect gin and tonic in 3rd grade, and he LOVED bartending at his friends' parties.
He doesn't drink. He used to have a drink every few months, but recently we've discovered that even one serving of alcohol shoots his blood sugar up and causes him to go into a *disgusting* mood. He hasn't had a drink since December 2010 when he picked an argument with me after a Baileys while we were at Universal, and the next day I made the case for it being something he just can't do.
Still likes helping people get the drinks THEY want and can have without becoming jerks!
I grew up in a strict, religious household. Not only did my parents not drink but I was told that it was evil and horrible and that I'd burn in hell if I ever took a sip. So yeah, I partied pretty hard in college and still drink frequently though in moderation. My brother is a "functioning alcoholic" so I truly believe the forbidden fruit thing.
I have a friend who is the youngest of 4 daughters. Same parents. Same STRICT parents.
The oldest got out of the house and married immediately; luckily she married a pastor, and they have a very sober lifestyle.
The next born, to this day, says that she misses *crack* over anything else. Nearly killed herself a few times with the drinking and drugs. This is an awesome, fabulous, NORMAL human being, but she went off the edge with experimentation, to the point where she can describe all sorts of highs, and just a few months back (at a wedding) told me how much she misses crack (but will never take it again b/c of its effects on her life).
The next sister has done some "light" stuff, and is a huge wine snob now. She has her own business, over 20 years now, and illegal drugs would negatively impact that, so she doesn't do them.
The youngest LIKES drinking, and wouldn't have minded smoking a bit of marijuana, but she was diagnosed with autoimmune hepatitis at 13, so even a little bit of naughtiness went too far with her. She almost never drank in college when I met her, drank a bit in grad school, then really had to stop it, because her body truly could not handle it.
2 incredibly strict parents = 1 "good" daughter 1 beyond-wild-but-reformed daughter, 1 strict with herself but likes wine daughter, and 1 would like to be wild but simply cannot daughter.
The climate of the CB is much more liberal since the last national election and the rule change here on the Dis about not discussing religion and politics. Many conservatives jumped ship.
YOu know that liberal politics doesn't mean liberal parenting, right? They aren't the same thing? In fact I'd say it's the opposite, since conservatives are all about laissez faire, as in "get out of my business and I'll stay out of yours".
