Happy 13th birthday to the most amazing nephew in the world! It’s hard to believe you’re officially a teenager today – wasn’t it just yesterday you were building pillow forts and refusing to eat your veggies? Watching you grow into this smart, funny, and kind young man has been one of life’s greatest joys. Whether we’re gaming together, laughing at your terrible jokes, or you’re rolling your eyes at my “old people” references, every moment with you is special.
This year marks the beginning of your teenage adventures, and I couldn’t be more excited to see all the incredible things you’ll accomplish. May your 13th year be filled with new discoveries, great friendships, and just enough mischief to keep things interesting. Remember, no matter how cool you get as a teenager, you’ll always be my favorite nephew (and yes, I know I say that to all of you, but you’re definitely the most favorite!).
