I'm a 19 year old college student in America, and I only drink at home or at a religious event where wine is an important part of the ceremony. I don't go to parties and stuff. The only exception to this was my recent vacation to Israel with a group of college students/young adults, due to the fact that the drinking age in Israel is 18. I happen to like the taste of some alcohol (not beer, though) but, that's the only reason I drink it at all, I like the taste, or it's religiously important. I don't go out partying (I have a strong fear of recieving a MIP), but I have the feeling that when my friends start turning 21 (this summer), I will have a few drinks with them, in private. I happen to feel that if at 18, you are considered an adult, then you should be an adult when it comes to drinking. And if you're not an adult, then why are you allowed to vote? And I may not even have a drink then, when my friends are 21, because it IS illegal (though I will still have them get cooking wine for when I make dinner
But, until I graduated high school, I never had a drink of alcohol without my father knowing about it, and being there. Parents are the ones who should decide for their kids, especially if it is illegal in their country. (I haven't formed views about other countries, where the drinking age is below 18, I haven't spent enough time considering it.)
I hope that made sense...
