My mother often told me my childhood. My childhood was not the same as muggles or muggle-borns, but they are also different from normal Wizarding Families. 

 So I was born at small town at London, really small that even people cannot find my town on the map. This small town was located at somewhat countryside area, even though I lived in London. This town did not had much wizards, so it was pretty much normal muggle town you can find anywhere around the world. My parents told me that when I was one month old, I accidentally set my father's head fire with somewhat supernatural powers and I continued to use magic and my parents and my younger brother Luke thought that this is real supernatural powers that is really abnormal. And as I grow up, I could do more tricks and things, that when I was 10, I could levitate myself. But my parents and Luke did not like this ability because they really do not believe in muggle religion and they did not like my abnormality. So I kept this secret because everyone in my school will think I am weirdo if I told them. Until that letter came which changed my life.
