My friend, Emma, purposely hid her birthday on Facebook because -- though she is not old at all -- she didn't want a thousand people "writing on [her] damn wall" and "asking where the party was." (Answer: "in my pants," Emma. The answer is ALWAYS in your pants.) Accordingly, she didn't show up in my list of birthdays, and by noon today, nobody had posted anything on her wall. Juuuuust as she'd planned. Right? WRONG.

Because my friends and I are like this, we wrote on her wall anyway, like, "HAPPY BIRTHDAY EMMA! IT IS YOUR BIRTHDAY WHICH IS GREAT! WHERE IS THE PARTY MY DOG?" and the like.



And then a funny thing happened: Facebook told errrrrrrrybody it was her birthday.



Intrigued, fellow Lemondrop editor Erin Scottberg and I tried a bold experiment: Will Facebook tell everybody it's your birthday if a bunch of people write it is on your wall? Does Facebook have some kind of bot that recognizes birthday well-wishing? I asked a couple of mutual friends to write messages of cumpleaños on Erin's pared:



And here's what came up in the feed:



So, because it wasn't Erin's actual birthday, nothing happened. (Except that a bunch of her friends who know that her real birthday is in November got all confused.)

While there isn't some kind of evil Facebook birthday robot, it's kind of lame that having friends like me can supersede your privacy settings.

Birthday Scrooges, consider yourselves told.
