Have you tried filming your interactions with them? Yes, i've been watching Dr Phil again!

Maybe it will help you or them notice things by watching them on a screen.
My second h once pointed out to me that i would wait until he left the room to ask him something. My "excuse" was that i didnt want to interrupt him while he was in the room with me, but if he was up and walking, that meant he was in interruptible mode, right? I think i apply computers too hard to my personal life.
He was like no, youre being a witch.
