I've never been to the US but it seems like drinking is alot more of a big deal there than it is here in Australia? I mean the legal age there is 21, what's with that? You can drive at 16 but can't even go to a bar until you're 21? That's fucked! Driving is far more dangerous than having a beer!
In Australia EVERYBODY drinks all the time. I don't know anybody who doesn't drink... and from the time you're 14 or 15 your dad starts drinkin beer with you! And the legal age to buy alcohol or go into a bar is 18 here. It's just normal behavior to get drunk every weekend... I think the entire weekend/social life in Australia is based around alcohol.
And it's not just coz "there's nothing else to do here" or anything because I live in a big city (I'd say Melbourne is like an LA style city but smaller, more the size of a Seattle or Houston?). Though one of my best friends is from a country town and going up there last year for his birthday, man their entire lives revolve around drinking up in the country! There it IS because there's nothing else to do hahaha. They drink during the day every day (though I'm drinkin during the day right now I spose haha).
It just seems weird sometimes when I watch American movies or TV shows and teenagers drinking is seen as being a bad thing, but here your parents start drinking with you in your mid teens usually I think.
I might be wrong though coz I've never been there, maybe the TV shows & movies are just way off but it does seem like a bigger deal there, and the 21 age limit thing is really fucked! I can't even imagine having spent my 18-20 years without going to bars & drinking.... that's where I spent all my nights!
