How to respond when someone wishes you happy birthday 
Post one thank you message. 
If you use social media frequently, you might get birthday wishes from acquaintances, old friends, and people you don't even remember. Even your friends are probably not waiting anxiously to receive a personalized response.

OPT:
 -One message to your wall thanking everyone for the birthday wishes is common practice, and unlikely to offend anyone. Here are some example responses : Thank you everyone for the birthday wishes! I'm having a great time! One man.
 -They may not know that it's near christmas time already. If you're unsure what you want to say, it helps to post a gratitude card at the end of each date and phone call.
 -If that's the case for you, aim to send one at least once a day. For instance, you could get a few quick text replies, return a comment or send a message letting them know that you wish for their birthday.
 -Be sure you're genuinely pleased to receive them. To post more than one thank you note, take out a paper plate and line it with tissue.
