The Cutest Origin Story of Mama Sir

One of the names that you are known by is Mamma Sir. I would love to know what is his story. There is a 5 year old child, his name is Abhay. The first time I started, his mother was a teacher in the school. So he came to me and he said, what is your name? I said, Mamma. Then he said, she is my mother. I said, she is a duplicate, she is my original Mamma. Then he made a mistake at home. He said, where is your father? He said, he is with his aunt. Then Mamma explained that he is not like that, he is Mamma Sir. So then he came up with this thing and he started calling me Mamma Sir.
