How do you wish someone a happy birthday on Facebook?

It’s an interesting thing to think about.

Do you post a birthday greeting, congratulations, or best wishes on someone’s wall or do you try to personalize it and send it as a message?

I was just wondering how people approaching talking with their friends virtually. I’m hoping that some will decide to share their answers below in the comments section.
