I thought about that man the whole time I was shopping, and knew I wanted to pay it forward. So, as I was returning my cart at the end of my trip, I gently shoved my cart towards a man getting ready to put his quarter in. "Here you go!" I said. He, in turn, held out a quarter to me. I said, "No thanks!" and walked to my car.
Next to my car yet another gentleman was getting ready to enter the store. He had witnessed my little cart exchange and commented that I had done my good deed for the day. I explained the kindness that had been done for me, and that I was simply passing on the small gesture. "It's the little things, right?" I asked. He grinned broadly and replied, "Miss, you are so right about that. Now you have a great day." And I did!
