My grandson, Chris, has worn glasses since the age of
three. When he was in the first grade he came home one day
very distressed. Wanting to find out what was the matter
his mother asked, "Chris, what happened today to upset you
so?"

He answered, "It's not fair that I'm not allowed to go to
the library."

His mother became very concerned and asked, "Why aren't
you allowed to go to the library?"

With a tearful reply he said, "Because, in order to go to
the library you have to have super-vision, and I wear
glasses!"
