Last Sunday, my friend and I was taking a walk on the playground when a girl came ride a bike at a very high speed. Then we heard a loud scream, that attracted our attention. We turned around and saw the girl struggling her feet, crying out for help. My friend and I rushed towards her as quick as we could and I had helped her to stand up. Therefore, the girl rode away immediately without saying "Thank you". I felt disappointing at her behavior. To my surprise, the girl came back with hot drinks several minute later. Seeing this, I knew I had misunderstood her and felt ashamed of me.
