You were Sirius Orion Black's son and you were 17 years old and already smoking like your father when ne was younger, your favorite Professor was your Defense Against The Dark Arts, Remus John Lupin, your father's bestfriend.

You were smoking outside, in the courtyard, at night, sitting on a bench that you didn't even notice that Remus was coming your way, you remind him of Sirius with your hair and attitude.

Remus wanted to scold you for being out the night, and because you're smoking too.
