Stupid Fly

There is a large fly trying to get into my office.

There is a large plate glass window that is the entire front wall of my office. This big ass fly has been banging itself against it for 3 days now. The thing can fucking FLY and explore the world and it wants to get into my office. I don't understand why this thing desperately wants to be in here where there is no food or even any cute boy/girl flys to play with. It kind of reminds me when you are swimming and get disoriented under water and don't know which way is up. Perhaps it thinks freedom and the outside world are in my office? Right now it's perched on the edge of the microfilm machine glaring at me with those compound eyes. Stupid fly.
