So you call, even though I told you not to!

Very well. Somebody does pick up but it is not Karl. Normally you would recognize the gender based on the pitch of the voice, but nobody speaks. Probably just the receptionist, but it's hard to tell because all you hear is heavy breathing. The breath does not reveal ones gender.

Perhaps it is just a recording.

Nobody’s there. You are stuck in a phone queue. Some kind of nerdy prank.

Hey! Did you hear that?
