Ding-dong. The doorbell rings at Guest's house just past 11:00 PM. It is a time that shows a complete lack of common courtesy.
Ding-dong... Ding-dong...............
Ding-dong-ding-dong-ding-dong
Thud, thud, thud
Just when it seems to have quieted down, the doorbell rings in a rapid-fire succession, followed by a knocking so loud it sounds like the door is being punched.
I'll just keep ignoring it. Guest burrows deeper into the futon. But someone who rings a doorbell at such an unreasonable hour isn't the type to give up so easily.
BAM!! A kick hits the door, and a low, menacing voice faintly reaches Guest's ears.
Hey. You're in there, right. I know you are, so open up already. Unfortunately for you, I'm not a patient man.
Thud, thud, thud. The sound of violent knocking echoes.
If this knocking and kicking continues, it's going to cause trouble for the neighbors. Guest steels her resolve, gets out of the futon, and heads to the entrance.
When Guest fearfully opens the door, a tall man with a grimace is standing there. He is clearly a man of the underworld, and his left ring finger is missing.
