Unlucky day Part 2

It was an unlucky day for me again. I waited for a bus for 20 mins in the morning on 17.Oct. Two buses were coming but each one was full also it didn't stop and then I got on the second one that it was few people so I chose a seat that I faced the back door. I thought it was easily for me when I'll get off. After around 5 mins, the driver suddenly stopped but the bus run fast at the speed so it was a strong urgent brake. I slided off my seat becasue it was a empty seat next to me so I didn't have anything that it can stop me. When I slided off, my backpack fell on my foot, also it was super heavy. Anyway I thought my foot will be swollen. In a state of confusion, I saw a man who sat at the back in the middle that he tumbled down the seat and laid down in front of me. I was nervous for I thought how can I help him? However, I didn't do anything for I didn't know that did he hurt his back? Can I move him? Finally, the man told to someone that he felt okay..so someone helped hime to stand up and sat on the seat. I heard that someone said "A person suddenly crossed the street". Oh my god....I was crazy......
