W:What a lovely cat!How long have you had it,Mr Brown?
M:Ha,that's my little Tommy.I found him when I was just thirty﹣five.Now five years have passed.
W:You didn't buy him from a pet store?
M:No.I found him on the street.He was homeless and very dirty then.I'm so lucky to have found him.He saved my life just one year after I brought him home.
W:How did he save your life?
M:You know I've suffered from a heart disease since I was a teenager.One night I suddenly fainted when I was taking a shower in the bathroom.Tommy found it,so he went into my bedroom and woke up my wife.She immediately took action and saved my life.
W:So you saved Tommy's life and in return he saved yours.
M:Yes.I guess kindness really pays off.
