I want you to know that I'm very sorry for my tardiness in wishing you a happy birthday.
I may have forgotten your special day, but I remember all of those days we spent together that were so special to me. I hope you can forgive me and focus on all of those special days, too
I may not get to tell you as often as I’d like because we are both always so busy, but you are a very important person to me and I’m very grateful to have you in my life!
You’re not just a cousin, but one of my oldest friends. You’re someone I’ve known my whole life, and I’m very lucky to have grown up with you by my side.
Have an awesome birthday, and a fantastic year ahead!
