All alone

I am in the office, and appear to be the only one on this floor.

I'm often the first one in when I manage to start at 7:00am, and it's not uncommon to remain alone until about 9:00am. Those first two hours of solitude are fine, but after that I start to get a little twitchy, particularly if I don't have anything particularly interesting to do.

I could really do with a juicy diagram right now.
