I am Mike. I have a neighbor He is a young man. He is not tall but strong. He always goes out at night and comes back home in the morning.
One day, I met him at the gate. He wore a pair of sunglasses, a black mask （口罩） and a black T-shirt. He looked unhappy. His wife asked him, "Did you use knives （刀） yesterday?" "Yes," he answered. I thought he Was ; going to rob （抢劫） a bank! Then he turned around and smiled at me, but I was arid of him.
The next day, I met him again. But this time, his son asked him, "Did you help people yesterday?" "Yes. A lot," he answered. Suddenly, I knew his job! He is a doctor. He always goes to the hospital and helps others at night. He usually wears a pair of sunglasses and a black mask because he is tired. He doesn't want to show his tired face to his neighbours!
