So sexist IMO.
To clarify, I have no issue with "My wife," but "The" anything I do.
My dad was out shopping once with my mum when he bumped into someone he knew loosely. The man said (in front of my mum, one of the strongest and most independent women I know): "Oh, is this Her Indoors?" Say whaaaaaaaaaat?!!! You can imagine her reaction!!! 😆
