Me and my fiancé decided together we weren't going to tell anybody including our parents the names we have picked for the baby. He has just got back from visiting his mum and dad and tells me because they wanted to know he told them what we had picked. He said they wanted to know in case we have picked silly names, one of the reasons we decided not to tell was because we didn't want to be influenced by other people. He justified it by saying we could change our minds anyway and at least he told me he told them. He can't seem to understand why I'm upset.
