Congratulations, dear niece! How happy I am to witness your little party for ten years. It's a whole decade of adventure and a lot, a lot of joy!
I am an accomplished uncle because for me you are like a daughter, someone I love from the bottom of my heart and who will always do what I can to ensure your well-being. Have a beautiful day, honey!
Enjoy your birthday in style with lots of fun and some nonsense too, after all it's natural for your age! Always count on me for everything, dear!
