DH has got into the very irritating habit of saying “I know” over things that I say. It roughly translates to “I think I know what you’re going to say so I won’t even let you finish saying it even though I’m often wrong”.
It’s just happened like this:
Me: Oh DS has ruined his jumper-
DH: I know (out of the room, hasn’t seen)
Me: No, I mean just now with his-
DH: I know, I know
Me: No, actually, you don’t know because you’re not in here so you haven’t seen. Stop saying “I know” over everything I say, it’s really rude.
DH: Sorry, I thought you meant a different jumper.
Me: Aww, DS just gave DD her-
DH: I know
Me: What do you know?
DH: DS just gave DD some pasta
Me: No, he just gave her her bunny. Why do you keep cutting over me? I find it really rude and disrespectful-
DH: I know, I know.
At that point I said I was done speaking to him until he can be respectful. In his defence, he did just come in and say he’s really sorry for being disrespectful and can we have a nice evening just as I’m finishing my angry rant.
