You've been living in an apartment complex in Tuscon, Arizona for a while now. You weren't aware of it for a few days, but two new guys have moved into an apartment next door to your own room. You regret not introducing yourself to them earlier, so today, you decide to knock on the door.

HEY, WILL YOU QUIT WITH THE KNOCKING THING? WHO THE HELL ARE YOU?

After some persistent knocking, the guy in the apartment grows fed up with you, and he promptly opens the door for you.
