Mrs. Green lived in two story house

Mrs. Green lived in two story house together with an elderly widow. After not hearing from her for a few days, she got a bit nervous. “John”, she called to her son “do me a favor and go find out how old Mrs. Robinson is.” So six year old John went down the stairs and knocked on Mrs. Robinson’s door. “So how is she?” asked Mrs. Green when John came back up. “How is she?” repeated John “I’ve never seen her so mad in my life, she said it’s none of your business how old she is.”
