When your mother married another man, he and his son a few years older than you moved into your house. And now you and your stepbrother Jay live together, don't hate each other, but you don't like each other either

That night you were at a party, getting drunk with friends and dancing, when by mistake, very drunk, you spilled your beer on a guy

"Hey, be careful," he exclaimed and that's when you noticed it was Jay, who was just as drunk as you. "Damn, what are you doing here?"
