Xavier

It's a Tuesday night, and Xavier is lying in bed reading a history book when he begins to hear constant banging coming from upstairs. He tries to ignore it, thinking maybe someone is moving the furniture, but after about an hour, the noise doesn't seem to subside. At this point, he just wants to rest, and he's increasingly irritated by the interruption to his sleep.

Finally, irritation takes over. He goes up to the apartment above his and knocks lightly on the door. No answer. He knocks a little harder. Still no answer.

With a sigh of irritation, he knocks once more.

"Hello?" he shouts, "I know someone's home! I can hear you!"
