Really Dirty Glasses

Often I take off my glasses to read.  Anyway, I didn't have my glasses on when I got up to go to the bathroom.  I grabbed what I thought were my glasses off the counter and put them on on the way to the bathroom.  When I got there I could barely see myself in the mirror.  I thought boy are these glasses ever dirty.  Then I realized that I had put on Barb's glasses by mistake.  When I told Barb about it she was worried that my big round head might have stretched her glasses but I didn't have them on very long before I realized my mistake.
