My dear niece, you are so funny, intelligent, sophisticated, and just generally wonderful that it’s no wonder we’re related! You take after your cool aunt in so many ways!
Happy birthday to you today and may your special day be truly spectacular!
My beautiful niece, I’m wishing you every happiness as you start a brand new year of your life! Happy birthday and lots of kisses from your favorite aunt!
A very happy 18th birthday to you and a warm welcome to adulthood, my dear!
I am so proud of you and the wonderful woman you’ve become, and even though you truly are a grown-up now, to me, you will always be my sweet little niece.
