One time I met an old American woman at a local city college. She seemed to be over fifty and was taking a class with her husband. She was sitting outside getting some sun. I walked up to her and said "hello" and we began talking. I told her something about myself and she told me about herself. She was very warm and friendly, just like an old friend. When I asked her, "How old are you" she told me that I shouldn’t ask that. Most elder American women don’t like that question, but she was very nice. She said, "Because you come from another country, it’s OK that you asked. I don’t mind. "（）
