Remarkable, unbelievable, and unreal are all ways in which someone could describe something truly amazing but also, much like in your case, something totally bizarre!
Just kidding with you, buddy! I’m sending my best wishes to the birthday boy today!
Happy birthday, pal! You know that I’m always looking out for your best interests, so just take care today when you’re trying to blow out the fireball on your cake!
Getting as old as you are can’t be easy, buddy! Luckily for you, when your legs start to give way at least you’ll still have a great friend like me that you can lean on for support!
You might want to forget about your birthday but I never could! I’ll take any opportunity to remind you that you’re getting older, my friend! Happy birthday!
I am a true friend, buddy. I’ll always remember your birthday but as a courtesy and out of respect for you, I’ve chosen to stop keeping track of your age!
In my mind, you’re only as old as you feel! Happy birthday to you!
