Sometimes when I’m driving, I get cranky with other drivers on the road with me and I want to yell at them, “Are you blind?!?!??”  I also know that a driver can get cranky with me when I don’t see them in my blind spot.  The whole blind topic reminds me, with a playful chuckle, of basketball refs in high school when my friends and I would watch a game.  If I thought some refs were particularly awful, I’d loudly sing “Two Blind Mice;” my variation on the children’s sing-along, “Three Blind Mice.”  I understand that I was being disrespectful and at that time, I didn’t care.  The whole subject of blindness can include being blind-sided, having blind spots, color blindness and sometimes we use the word, “blind” to mean oblivious or clueless, being unaware.
