Happy birthday to my dear brother from the same mother!
I continue to count my blessings and especially so on your birthday, for the simple fact that I have the best brother in the world. I can’t imagine being anyone else’s sister.
It’s difficult to convey just how much you mean to me in a simple birthday message but I hope you already know that you’re not just a central person in our family, but also one of the most significant people in my life.
I’m sending all my birthday love and best wishes your way today, my dearest uncle.
