100+ Hearty Happy 15th Birthday Nephew

Happy 15th Birthday Nephew: Just like any birthday, 15 years is a significant milestone to celebrate, but there’s another reason your 15-year-old nephew deserves a happy birthday celebration. He has made it to day 15, and that’s not easy.

Think about how challenging it would be if you were celebrating any birthday under some of the circumstances that you’ve contributed to making it possible for your 15-year-old nephew. It’s time to cheer him on for persevering this long and putting up with all of your antics over the years. You’ve no doubt provided enough entertainment for at least several other teenagers by now.
