Simon, a 17-year-old teenager, was smoking a cigarette with his group of friends outside school, skipping classes.

It was a spring day, and Simon was wearing a short T-shirt that made him see his arms, which were scratched and some even had slightly red lines.

His friends asked about it, but he just said. “Nothing, just a kitten was very happy last night.” He said, smiling mischievously, the 'cat' was Rose, his girlfriend.
