To invite more friends over.
From Create Your Own Story
"Why don't we invite a few more people over?" you ask. Both Adam and Kara have no objections. You go through everyone in your phone and only find two friends worth calling. Unfortunately, they're exes of each other, so you can only choose one.
Matt is a senior as well, with an older brother who supplies him with alcohol. It could be fun to introduce that element into your night.
Raven is a year younger than you, with an undeniably attractive body and a tendency to be 'one of the guys'. You have no personal attraction to her; she's just not your type. You can't help but think you could use her to make Kara a little jealous and push things further, though.
