Sometimes, it shows up when I'm not expecting it, just to freak me out. Did I send it back to me from the future? If so, what was I thinking? Don't I know that I can't be trusted with such technology?
Occasionally, I'll step out, walk up to myself, and yell, "Stop it!" I'm not sure if I have a good reason or if I'm just messing with myself. (or Am I?)
