"Every year, I’m in awe of how you continue to evolve. Somehow, you keep leveling up in strength, grace, wisdom, and heart. You’ve always been powerful, but lately it feels like you’ve tapped into an even deeper layer of yourself, calmer yet more unstoppable, grounded yet still dreaming bigger than ever."

You already know, I’ve got you in every lifetime. No matter where life takes us, I’ll always be right there cheering, protecting, and loving you through it all."

"You and me forever, kiddo," she added, "Happy birthday, my spectacular stunning sister."
