I’m sending the very best birthday wishes your way today, my adorable little cousin sister! May your special day be a beautiful one full of love, joy, and happiness!
My beautiful sister, you have a heart of gold and a soul so sweet that it’s only right you have the most magnificent birthday this year. Happy birthday to you.
Birthday gifts are overrated I think, sis, so starting from now I think we should just exchange sweet birthday wishes instead! Happy birthday, my dear!
