Jeack, my birthday is the coming Wednesday, same thing expecting maybe a text "Happy Birthday". I will simply reply thank you. I don't know about the Facebook option, to me, I still have some family and friends who are happy to acknowledge my birthday, so why shouldn't I reply to their messages. Just don't make is seem like you are sitting on Facebook all day waiting for them.
