When I was about 6 years old I lived in Kenya. There was a lot of and there were always street children on the roads asking for money. There was such a big divide between those children and me and I grew up very aware of being so . We had a wonderful and very kind driver, John, who had been working with my for decades. He used to take us to and from school. One day while we were stopped in traffic a young street child, probably no more than 10 years old, with a friendly greeting, “Hi, John!” He the car and shook John’s hand,. John then gave him a little bit of money and waved him off with a smile before we carried on our way to school. I had watched the whole incident completely . John had a large family himself and had to work very hard to make ends .I knew that he didn’t have any spare money. So, of course, at that age I couldn’t understand why he would be giving money to the child. “Who was that?” I asked. “My friend,” he replied. “I see him every morning on my way to work and I give him a little bit of money.” Unable to comprehend, I asked, “Why do you have to give him money every morning?” John replied, “So he can use it to buy some food.” It was probably at that that I understood what kindness really was. A person who was in a difficult situation himself still found some money to for a child who needed it. Even at the age of 6 that had such a great impact on me. I didn’t have any money, but I wanted to too. So when my grandfather gave us a chocolate bar after dinner every Friday, I would mine up so I could give it to John to give to his friend.
