I react badly to "challenges." Throw down a gauntlet and the worst part of my personality comes out. The man who became my husband remarked "women can't handle tequila." (Oh-fucking-YEAH?) Actually, I'd never had tequila, but I rose to the challenge and decided to drink the man under the table.
I did. I walked up the stairs to the bedroom, mocking him happily, as he crawled up the stairs on his hands and knees.
I'm really, really short on amusing drinking stories, so I have to make do with the ones I have.
