When I was ten years, I used to play slot machines with my cousin, we always win although it was difficult, we won a lot of money.
When I was fifteen I used to live alone in mexico city in a departament because my house is far from the school where I study, I used to like a lot because I could arrive when I wanted, I felt free and independent, but my parents did not like and so I return to my home.
