I walked to the Da An Park this morning.When I walked around half circle of the park,there was a black guy closed to me and said"How are you?"At first,I wanted to ignore him."How are you?"He said it again.I thought that people say"Chinese people are impolite,they never say hello to a stranger."So I answered him"I am fine,and how are you?"He was closer to me"Why are you here?"He asked."I am walking!""May I have yourphone number?He asked."NO!"I said."Why?I want to make friends with you.""But I don't want!"I walked quickly.He was chasing me"Can you give me your phone number?"He looked very young,"May I ask you,how old are you?"I asked."I am 30,and how old are you?""Ha!Your age is same as my son's."I lied to him."
