Dear Abdullah ,
I am writing to apologize for forgetting your birthday. I know how special your birthday is to you and how much it means to celebrate it with your loved ones. I am truly sorry for letting you down and not being there to share this special day with you.
I want you to know that my forgetfulness was not intentional. I have been incredibly busy with my new job as a developer and have been consumed by the demands of my work. I have been working long hours and have not had as much time to devote to my personal life as I would like.
I understand if you are upset with me and I hope you can find it in your heart to forgive me. I promise to do better in the future and make more of an effort to prioritize our relationship. I love you and am grateful to have you as my brother.
I am dedicating this song to you, i hope that you will forgive me with love after listening to it.
Sincerely,
Zaid
