On a trip to California, my family stopped for lunch. As we walked toward the entrance to the restaurant, a man, with a            beard and dirty hair, jumped up from a bench outside the restaurant and opened the door for us．Regardless of his            , he greeted us in a friendly way.

Once inside, my daughters whispered, "Mom, he          . " After we ordered our lunch, I explained, telling the kids to look            the dirt. We then watched other customers approach the restaurant but many             him. Seeing this rudeness truly upset me. The day I became a mother, I had determined to set a good             to my children. Yet sometimes when things didn't go right, being a good example was             . When our meal arrived, I realized I had left the car-sick pills in the truck．With the windiest trip ahead, the kids needed them, so I           myself from the meal and went to get them.

Just then, the "doorman" was opening the door for a couple. They rushed past him without even acknowledging his            . Letting them in first, I said a loud "thank you" to him as I             .

When I returned, we talked a bit. He said he was not allowed inside             he purchased food. I went back and told my family his            .Then I asked our waitress to add one soup and sandwich.

The kids looked             as we had already eaten, but when I said the order was for the "doorman", they smiled. When it was time to           our trip, I found the "doorman" enjoying his meal. Upon seeing me, he stood up and thanked me heartily. He then           out his hand for a handshake and I gratefully accepted. I suddenly           the tears in his eyes—tears of gratitude. What happened next drew great astonishment: I gave the " doorman" a          . He pulled away, with tears           down his face.

Back in truck, I fell into deep thought．While we can't choose many things in life, we can choose when to show gratitude．I said thanks to a man who had           held open a door for me, and also said thanks for that          to teach my children by example.
