W: Hello, everyone. In today’sprogram, I’d like to share a true story of mine. One day, my friends and I hadjust finished lunch at a hotel when it started to rain heavily. When it became lighter, I decided to brave the rain to get my car and go home. It was parked three blocks away. My friends argued I shouldn’t go because at that time, I was due to give birth in three months. I promised I’d be very careful. One of them wanted to come with me, but I insisted she stay with another friend who needed help with her baby. When I walked to the first cross roads, a taxi stopped and apassenger came out with an umbrella. Before I knew what was happening, he walked right beside me and told me he would walk with me to where I would go. I refused, but he insisted. During our walk, he kept telling me to walk slowly.When we got to the car park, I thanked him, and we parted ways. I did not get his name and may not even recognize him now. Did he purposely stop for me? I’ll never know.
