Who am I ? I was born in 1953 in a undeveloped country. My father was a railway worker in a cargo station. My mother was a nurse and worked at home. In our house yardwe some trees: two guavas trees, sugar canes, a orange tree and an evocado tree. I didm't have toys so I played climbing up trees, making holes in the ground and filling it with water and I dreamed fishes swimming there. Some time I made ways and I imagined toy cars runing on it. When I was seven my mother got pregnant and my father asked me what name I would like the baby to have would if He was a boy. I said: Mário Augusto da Cruz. After the birth of my brother my father showed me the birth certicate and said: the name of your brother is Sebastião. I examined the birth certificate and said to my father: No, here is writen: Mário Augusto da Cruz. My father laughed and told to my mother: Luiz knows how to read. After that, I have always enjoyed reading. Nowadays, I'm a retired physician.
