I was blog hopping tonight and ended up reading a post that reminded me of something that happened a long time ago.
My mom owned and ran a hardware store. One day a young man came in looking quite forlorn. She asked him what was wrong and he told her that a hose on his car had broken, draining the anti-freeze. He was on his way to a job interview in a city about 100 miles away and didn't have the money to pay for car repairs because he had been out of work for some time.
Mom had the necessary hose and antifreeze on hand and together they managed to fix the car. When the young man asked how much he owed her she told him there was no charge and handed him enough money for gas, food and lodging for the next several days.
It was quite a bit of money and he didn't want to take it, but finally did. He asked for the address so he could repay her and mom told him to pass it on by doing something nice for someone else some day.
Many, many years later my dad broke down on the road during a raging blizzard. Although the highway was virtually deserted, a man stopped and offered to help. When the two men determined that they couldn't fix the car, he gave my dad a ride in to the next large town to call for help.
While they were driving, the man told my dad that he always stopped to help stranded travelers because of a woman who had helped him when he was young, asking only that he pass it on.
