Dear Sirius,

I thought that you were rude to me because somehow you have felt that you're gonna be a Gryffindor but today my thoughts have changed

At common potion class the professor wanted that everyone to be partners with someone from another house, I thought you could be my partner. You chose a blonde girl and you were having so much fun, she was a Slytherin too so your behaviors are not about the houses

I need you please, you're the only one who understands me

Sincerely,

Bellatrix.
