Something in my mouth was bothering me. I could not figure out if I had something in my teeth or had developed some sort of lesion on my gums or…
I was standing in front of the bathroom mirror making various faces, attempting to get a view of the issue. All of sudden I realized that Pennywise was staring at me out of the mirror in the guise of my father. Well, at least the way I was contorting my face so reminded me of my male parental unit. One time when I was taking his picture and he, perhaps, preferring that I did not, was making faces at the camera lens. That is what I saw in the mirror.
I probably interpreted it as Pennywise as I finally got around to reading some Stephen King. First I read his initial novel, Carrie, and then It. Of course, It features a monster that frequently appears as a clown and in mirrors.
And just to do him justice, here is a better photograph of my father.
