I’m truly blessed that we’re related, but even if we weren’t cousins we’d still be best friends until the end of time. You really do mean the world to me, my dear.
I always have and always will wish only the very best in life for you, so may this birthday of yours bring you great prosperity, and may there be no limit to your success.
On your birthday, I wanted to tell you how amazing and perfect you are, and that I would never want you to change even one single thing about yourself.
But then I remembered how annoying you can be sometimes, so maybe you could just change that?
