When I was in middle school, I was on a family vacation in Washington DC. I found there was a homeless man down the street.
On our final day in the city, when my parents went for an evening walk, I went out of our hotel room and ran down the street to the homeless man.
He looked at me, surely not expecting anything from a middle school girl. I asked him what he wanted to have for dinner. He replied "Bread and water". I ran into the store and bought a big bag of bread and a bottle of water. I ran back with a smile on my face and handed the bag and the bottle to him. His smile has been in my mind ever since.
I came back to the hotel room and when my parents returned, my dad told me he had a story for me. He asked if I remembered the homeless man down the street from our hotel and I shyly nodded. He then told me a story. As they were returning from their walk, they saw the homeless man was sharing a bag full of food with other homeless people around. They were all smiling and laughing as they ate.
I smiled at my dad but I have never told him to this day the other half of the story. Till today, I still haven't forgotten that man's smile but I wish I had the courage to do this more often. One small kind action can begin a ripple effect(连锁反应)of kindness. So please,share a smile and do something kind for the people in need.
