Dont get me wrong, I definitely know you mean. Seeing yourselves as a unity is important and reflecting that in the way you talk can be beneficial, words carry meaning after all.

But, I heavily disagree that you can deduce someones devotion to a relationship or their ability to be a parent from a single sentence posted in a joke. And even if someone does not talk like that at all, they can still feel differently.

Also, funny you mention my wife, because she talks in a very peculiar way. Most often, when talking about herself or her pregnancy, she would say things like "your back hurts" or "you have nausea" like in a general sense, but it only applies to herself. I sometimes say "you mean you do" or something, but she doesnt even realize which words she uses. Not everyone forms sentences like a mathematical equation. I know I do, thats why its been difficult to understand that others dont necessarily and that brains work in different ways.
