After all these years, I hope you know that you’re just as close to me as a brother. You are someone I am proud to call a friend. Happy birthday to you.
You are the best boss I've ever had, a true mentor, a great leader. Today I want to wish you an awesome birthday, and lots of joy and success evermore!
I'm sending the very best birthday wishes to you today, sir. Someone of your seniority deserves the utmost respect, and you certainly have all of mine.
