An unusual visitor

Today is a warm winter weekend. My school wants students to go out to study to learn. Early in the morning, my friends and I walked out of the train to the school where the extracurricular activities were held. Along the way, I suddenly remembered that I still hadn't eaten this morning. I walked quickly into a bakery nearby. Waiting for the hot bread to come out to the oven, a guest suddenly appeared. It was a man with a brown cloak and a wool scarf covering his body, so his face could not be seen clearly. He put his hand on the sign, ordered a butter sandwich, but he still didn't say anything but the shopkeeper understood and went to work for him. I quietly asked the shopkeeper: "Is he dumb?" The shopkeeper smiled slightly, replied softly: "No! He learns signs to talk to others." I wondered: "Others?" The saleswoman is the same, holding the bread in her hands, wrapped it in a paper bag and handed it to the man. I watched, seeing that he was giving bread to the poor children around, they did not speak just using gestures to make the man understand. It was then that I realized that it was too late, and I flew to the train station. On the train I still remembered that unusual guest, he was such a kind man.
