Answer the door.

From Create Your Own Story

You open the door only to be greeted by the sword tip of none other than your neighbor, Dapple. "Lo' Chris," he says, "Don't mind if I come in." He pushes you back and forces himself into your home, swishing his sword about in a flashy manner.

Ask him what he wants.

Get angry.

Tell him you'll call the guards if he doesn't get the fuck out of your house.
