If you had a private discussion with a friend about parenting methods and...?

One of the reasons I don't have a facebook page....things that should not be public now are. I would be annoyed, and I would not be quiet about it.There is nothing you can do about the posting, and that does not even really matter, your opinion should not change whether it was made public or not, it is your opinion and that is OK, but you should say something to your friend about the idea of privacy and things that come up in conversation between friends are no ones business.
