Two weeks after my twenty-first birthday, this girl I only casually knew as a friend came up to me and told me I was so hilarious and fun at my birthday party. I said, "You were at my birthday party?"
She wasn't amused. I didn't remember seeing her there. Her roommate came up and asked me if I seriously couldn't remember seeing her at my party. I actually couldn't. So, her roommate informed me that I had been making out with her there. Ooops!
