What is it with people who absolutely refuse to understand that it isn't about them and their lack of a concept of privacy? I would also like to slap my SIL upside the head and tell her it is not ok to post baby pictures of her relatives all over the bloody internet. Post whatever pictures of yourself you'd like, but not of other people without their permission. Also also, children over the age of five are not babies, for frak sake. JFC.
