We must be a very smart group. It's amazing how fast our minds come up with answers when confronted. I was caught with dark eyes by my wife some years ago. In a matter of a second I thought."I thought I really cleaned them good, I can't believe she could see anything" My answer came swiftly. "I'm just tired" she kept staring, even a better answer jumped out. "I'm really tired" followed with a yawn.
