What I Have Found 我发现了什么

 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. 
我隔壁住着一个奇怪的老人。他话不多，喜欢在小区里闲逛。有一天，我看到他在寻东西，我很好奇，就问他了。他说他在找钥匙。第二天，一个男孩来感谢老人帮他找到钥匙。我发现那位老人原来是个好人。
