I could just say "happy birthday" and move on, having just stated something so formal for something so special.
But I won't. Because if I did, it'd probably end up with a "happy bday" => "thanks" => never talk again.
Actually, no. I'll tell you happy birthday. I'll wish you a happy new year. I'll pray for your wellbeing. And ask to be friend.
In that order.
Happy birthday sir. May the force be with you, and may you have all your wishes come to conclusion.
Drop by for a convo, perhaps even a rp or a chat or two, and make a new friend.
And have a nice day
