Guys, remember: when you come to your friend's place to pick him up and find him outside talking to someone, you have to shout and interrupt him. Don't even bother getting out of the car, coming to his field of vision and letting know that you've arrived in a non-intrusive way. You don't have time for all these courtesies to behave like a decent human being since you're in a hurry on your way to get smashed.
