A Beggar or Not?

Many people might may have an the impression that a beggar must be a dirty man in tattered clothes. I was one of them these people 1 until last month. One day, I was having my lunch at home when there was a knock on at the door. When I went and opened the door, . Then I saw a man standing in an old but clearn clean suit and with leather shoes stood outside. I did not know him. I asked him whether if he was finding looking for someone. However, He smiled and asked me for a meal and a glass of water. In return for this, he stood on his head and sang songs. I gave him a meal. After he ate the food and drank the water, . Then he went away. Later a neighbour told me that he is a beggar. I have never seen a beggar like this. I do not think that they this sort of beggar do not regard themselves as a beggars. Maybe, they think they make a living by singing. What do you think about this?

I don't think they are beggars because you accepted their entertainment as payment for their meal. 

1.  At a first glance, this is not clear.  You can mean you were one of the beggars.  One has to read further into the essay to realize you were of those people with misconception of how a beggar should look like.
