There is an old man in our school’s small shop. He is in charge of the shop. Whenever I see him, he is also smiling. Every student likes to talk to him, for this old man knows a lot and he is very young in mind. Once I lost my wallet, it is him to remind me to pick up it. He is such a kind man, I like him so much.
