Happy birthday to the person who was once my closest friend. I'm not sure where to start or if you'll even read this, but I need to say it. Despite our friendship ending, I've never forgotten the good times we shared, the laughter, and the memories. You were my first friend here, and that means so much to me.
I regret how things ended between us. I was going through a tough time in 10th grade, and I lashed out at you. I'm deeply sorry for my actions, and I understand if you can't forgive me. But I want you to know that I've grown from that experience, and I've learned to appreciate the value of true friendships like ours.
I'm glad to see that you're doing well, I know we may not be friends anymore, but I wish you all the happiness in the world. You deserve it.
As I look back on our time together, I realize that our friendship was a special one. We may have drifted apart, but I'll always cherish the memories we made. I hope your birthday is as amazing as you are, and I wish you all the best in your future endeavors.
Take care, and I hope you find happiness in everything you do.
