It’s your special day today, birthday boy! Just don’t let all of the attention go to your head because after today that attention won’t hang around for long!
Happy birthday and best wishes to you today, my dear best friend!
I know your secret, girlfriend! Out of all the messages you receive on your birthday today, I know mine is the only message you’re really interested in!
Happy birthday, sweetie. I hope your special day is as special as you are to me, and as special as I am to you!
