You see beers all over a table so you lift each one up until you find one half full and chug it when no one is looking.), and some represent a pain and sadness we are thankful we'll never know (12. You pass out at the party. And the next morning there is writing all over your face and limbs.). But we're not about to ridicule a gal for enjoying herself. Our rules for maintaining a ladylike demeanor during a night on the town: liquor before beer and be sure to know the name attached to any tongue in your mouth.
