Apology Letters to Friend.
Forgetting Your Birthday

I am truly sorry for forgetting your birthday. I can’t believe I let that slip by, and I know how special that day is to you. It was thoughtless of me, and I want you to know I take full responsibility for my carelessness. I understand that my forgetting your birthday might have hurt you, especially since it’s a day when you deserve to feel celebrated and cherished. You’ve always been there for me on important days in my life, and I really let you down this time. It’s not just about the day itself; it’s about the thought and effort that goes into celebrating someone you care about. I regret not being the friend you deserve. I can’t undo it, but I genuinely want to make it up to you. I’d love to take you out for a meal or plan a day together, just to celebrate you properly, even if it's a bit late. More importantly, I want to make sure this doesn’t happen again. I promise to set reminders and be more mindful of the important dates in our friendship. I understand if you need some time to process this. Your feelings matter to me, and I’m here whenever you’re ready to talk. I hope we can move past this together.
