In December of 2006, I was the single parent raising my daughter whom was six years old at the time. I didn’t have much money, and I wanted to buy a Christmas tree. I took my daughter along with me. As we were choosing a Christmas tree within my budget, my daughter wanted a tall tree than that planned one. I told my daughter we can’t afford a taller tree. Someone must have heard of our conversation. When I went to paying for the tree, the clerk said the customer before me had paid for my tree. I shocked. I was very thankful to what the stranger had done for us. That day I promised to me that I would pay it forward.
