Yesterday morning, I met an old lady on my way to school. She was laying on the ground and looked in great pain. I walked to her and helped her sit up. After she felt better, I asked what had happened to her. She told me that she suddenly felt very sick and fell down. I stayed with her and told her to call family members. I didn't leave until hher son came. The old lady and her son kept thanking me, but I just told them that it was something I should do. Although on that morning I was late for school, I felt happy.
