By the window

There's lousy cell phone reception in office where I work, unless you come stand right by the windows. That is, right on the other side of my cubicle wall. But you have a phone at your desk, so why would you need to use your cell phone? Oh, because you need to argue with your significant other or a collections agency or anyone else who needs a good arguing with and you don't want your coworkers to overhear. Just, I guess, me.
