Happy birthday! On your birthday this year, I just want to take the opportunity to thank you for all of your help and support! You’re a great friend and coworker!
I’m sorry I couldn’t be there to wish you a happy birthday on the day, but I’m sending you your birthday wishes anyway! Belated birthday wishes to you!
To my wonderful son on your 25th birthday, know that not a single day has passed where I haven’t been grateful for the blessing that you are. Happy birthday!
