Khadija: in the metro

Once I was on the underground, and several young men entered the coach. They made a lot of noise, and that bothered me. I asked them to keep it down. One of them came towards me and shouted in my ear: “And who will stop me?!” He continued shouting at me and sat next to me. I punched him on the nose, and silence fell upon the coach. I opened my white cane, stood up and got off at the next station. I am sure I broke his nose.
