Glasses lost?

Tuesday evening, I thought it was a prudent idea to take my reading glasses with me to an off-site company class I was to teach.  Carrying papers, an umbrella, and the glasses case in my hand, was sort of awkward.  Somewhere I laid down the glasses but I don't know where.  I haven't found out yet if I left them at the company or in a taxi.  They may be retrievable in both cases.  I hope.

 

For now, reading is like reading in a haze.  I can see the text but not sharply.  A small text book I read every night is now unseeable.
