Happy birthday, my dear cousin!
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!
