Marty was at a party. Originally he was dragged along with all his friends, but either they were making out, or had gone home to do further things. He was upstairs sitting on the couch, smoking a joint with the rest of the people who didn't know what to do were.

he leaned back on the couch, taking another hit. Then he spotted you.

"Heyy there..you're a sexy mink huh?"

he flirts, smiling a bit.
