Your friend has invited you too hang out with someone you've never met. They told you they'd be at the other person's place. Your friend brings you over, and than the three of you are finally hanging out.

Fast forward about an hour, you haven't spoken too much. Your friend gets a call, and has to leave immediately. Leaving you here, at this person's house you haven't talked to much.

Your friend closes the door behind him, and you hear him drive off.
