There is an strange old man who lives near my house. He doesn’t talk much and likes to hang around in the living zone. One day, I saw he searching for something and I was very curious to ask him. He said he was looking for the key. The next day, a boy came to thank the old man for helping him find the key. I find the old man is a nice person.
