"In today's social experiment, I have officially proven that facebook turns people into sheep." There was more. It did not make it better. It felt like, oh, look, your shoe is untied, and a slap in the face.
I did not, actually, wish this person an HBD. I was, actually, feeling mildly guilty for not doing so, but I had some issues with her before this. However, calling people sheep was a bit over the top. That is not socially awkward. That is something else. So, unfriending occurred next. Followed by finding the birthdate in question within under 2 minutes. Because birthdates are not private information. Pipl gave me the year and ancestry.com provided the full birth date. If you've voted, gotten a driver's license or any number of other things, and your name and place are not _too_ common, I can use ancestry's collection of databases to find your birthdate. The followup, weak excuse of, you can see why I don't want FB to know my birth date, makes no sense.
FB = Facebook
HBD = Happy Birthday
