I think at some point, especially when the same issues reappear with people in your life and your reactions to them, it can be helpful to examine the connections between what people say and do and how you interpret that. People operate with a "confirmation bias" where we take in selective information that confirms what we already think. For me, and especially when my PTSD symptoms were more active, my assumptions and interpretations boxed me in to the same old, same old. Being free of that, and relating to people from a place of openness and at least an attempt to attune to what they are communicating rather than my distortions of it, was helpful to me. I'm not really there entirely, it's still an issue for me. But IMO, concluding that where someone puts the tissue box is some huge thing about who they are is creating drama that just doesn't exist. It's just an object, and the number of places where it could conceivably be located are enormous. There is no one right place to put it. I think it's wacky to think that where you think it should go is the only reasonable way to do things.
