Flies!

I don't know what it is about this place but I swear it is infested with flies! We get flies in our house all the time and I am going crazy. Literally. I sit and watch the windows for large chunks of time trying to understand how they get in. I think they are coming through a little slit in the window. Jer says it is for venting. I don't care what it is for I hate flies and will do anything to get rid of them. So, I am duct taping the windows.
