Dear Sirius,
I miss you so much. I miss every moment I spent with you and I wish I could have spent more time with you. I know I have been very busy with everything at the moment, but a minute doesn't go by when I don't think of you. You made me feel like I was close to dad and I loved listening to your stories from when you were at Hogwarts. You were my fatherly figure. I love you so much and nothing can ever change that. I hope you carry on making mischief up there with dad. But please remember that I am with you in whatever I do.
Remember that I love you.
Harry
