I used to be very confident in my English communication ability, but that day was the day that made me realize that I was very weak. That day, I met an elderly man who was very confused, looking back and forth. As if to express myself, I went to ask him what his problem was. He told me in English but somehow I don't know what he was trying to say. Suddenly a man came running, communicating with him in a very professional manner, who was just the receptionist in the opposite hotel and finally helped to solve the problem for him. When asked how this person could communicate with him, this person only answered that he was a native of the southern part of the United States because he was a old men, so he had quite old English so if he did not communicate. It is difficult to understand for a long time.
