The Smudge Issue

Here's the thing, I have a smudge on my monitor. It's been there for about two weeks. Yes, that's right two weeks. Ever since I started the edits for Harriet Beamer. What do you suppose it means? I could very easily clean it off but for some reason I don't want to. It's not really in my way or impairing my vision. I tried to take a picture of it. It's not that I'm lazy. Ordinarilyy, the spot would have been gone by now. I will clean it when I finish the edits. It will be my reward for when the job is done. Most writers I know celebrate with chocolate or a nice dinner. No, not me. My celebration will be a clean screen. Does that make any sense? Any of you psyche majors out there who can tell me the psychology behind my smudge. Is there some deep-seated, smudge-related thing going on? How about you, is there a smudge in your life you can't seem to Windex away?
