Like I said people have different experiences when they drink. I know someone who will laigh at everything when they drink and others that just sit there silent not that bothered.
Absynthe, really? I have never had it in larger quantities but it is weird stuff. Nice flavour though.
That stuff'll put you in hospital if you're not careful. If I remember correctly the proper way of drinking it is to use one bottle cap's worth, mixed into a pint of water with sugar. The youth of today however *sighs* just order triples and are surprised they end up in wheelbarrows. O to be young.
As for hangovers, some people get them differently. But trust me, they get worse as you get older. Exponentially so.
If you're 12 then how have you had wine, champagne, and beer? I'm 13 and I've never had any alcohol in my life, but when I do become 21 I believe that I will only have red wine, and champagne since my brother (21 years old) has had multiple kinds of alcohol, and says that almost all beer is disgusting, and since both of my parents hate all alcoholic beverages.
