Where did I put my glasses?

I must be getting old. I'm forgetting where I put things. I was settling down to read last night when I couldn't find my reading glasses anywhere. I thought I left them on the nightstand where I usually put them, but they weren't there. I looked under the bed, in the drawers, and then all over the house. In the end, I wound up spending the night trying to find my glasses instead of reading. I hope they turn up today.
