Well I don't think that it was intentional, or that she really forgot her. It's probably due to the fact that Becky doesn't post here on the boards. She didn't mention her own husband, Miss Paella, or my wife either probably because we don't see them as members of the board and we just automatically include them in as spouses or children of the actual board members.
It's natural to only make refernce to the actual board members themselves when discussing these things.
