The clock ticked by, second by second, minute by minute.
I couldn't stop looking at the time, my eyes constantly drifting between the clock and the doorway, the muscles in my neck getting tenser and tenser as the what ifs drifted through my mind.

This was why I didn't like visitors.
Especially ones who didn't specify a specific time they were coming by.

How long would they stay? What would we talk about? Would it be a good visit or one I would come to regret?

Ding. 

I jumped. 
Heart pounding. 
My visitor was here. 

The moment of truth.
