where the hell are my glasses?

Have you seen my glasses? I was spotted without them late Friday evening, and when asked where they were I am told I replied "don't worry, I know where they are." What did I know then that I do not know now? I've searched high and low for them to no avail and damn it, I just bought six replacement frames that do me no good without the lenses. My plan to never have to buy new glasses has been foiled. Shame on me.
