Unintended Monocle

This past Tuesday morning, I picked up my glasses and prepared to clean the lenses before leaving for school. I noticed that the left lens, which has displayed a propensity for falling out of late, was missing. I looked around for a few moments to see if I could find it, without luck. Having no more time for the search if I were to arrive at school on time, I went to school without my glasses.

(I'm fairly fortunate that my eyesight isn't really that bad. I can even drive—legally—without my glasses if I need to. But if I spend a lot of time looking at a computer screen without them, I start to get headache. Did I mention that I spent most of last week entering grades into the computer before the end of the quarter on the 29th?)

I was unable to find my glasses on Tuesday night. Nancy helped me look, to no avail. I looked again briefly on Wednesday morning, again without any luck. So I went to school again on Wednesday sans spectacles.

Nancy went to her Mom's house on Wednesday night while I stayed home and graded papers. And an interesting thing happened while she was there: she found out that her Mom had discovered a lens from a pair of glasses and couldn't account for it. She brought it home with her. Sure enough, it was mine.

The really odd thing about this was that I hadn't been at her Mom's house since the previous Saturday night.

This means that I had to have gone to church on Sunday and to school all day on Monday with only one lens in my glasses. Without realizing that fact.

Good scientists are supposed to be observant, right?
