Thirty years ago, my world almost fell apart. I had operation and was fired. In a few weeks, I saw an ad about a Spanish festival. Although I was very upset, and I decided to go. Here, I met a gentleman with who I chatted for hours. A few day later, I came home to found a letter at my door. It was from that friend. Inside the letter was a 1,000-dollar check to help me through his hard days. Sixteen years later, I met a family that bad needed help. I gave them enough money to get through. They called me their angel, but I told them I once had an angel, also.
