Yukon Jack when I was 5.
My dad and my mom were having a party and I wanted to drink what everyone else was drinking so after 30 minutes of being a little brat my dad finally said, "Fine, don't blame me if you don't like it."
That did not end well for me.
I couldn't drink anything but water for the whole week.
Now I love alcohol and I am 19. Mmm, beer, wine, vodka, rum, whiskey. YUM! I got drunk for the first time when I was in London visting my mom at 12 (she lives there, has since my mom and dad divorced) and she let me get plastered. I got hammered at my dad's retirement party after two keg stands.... Hmmm... I am a boozehound D=
