A recent experience that I had while Donna and I were on a trip to Palmer College in Iowa is worth repeating for the life lesson that it brought to me. On our way through the San Francisco Airport, I noticed a woman being escorted by an airline attendant. As we walked to her side, I noticed how the sun glasses she was wearing seemed out of place on this gray, overcast day. Then I saw her white cane sticking out of her carry-on bag. She talked with the attendant as she took her seat in the front of the bus which transports passengers between terminals.
