I've noticed this with my ISFJ mom and my INFP cousin, so I'm guessing it's Si vs Se: they will ask me where something is or if we have something without even looking, or complain that they don't know where something is. I always know where things are. I pretty much know where everything I own is. Not only do I usually put things in the same places, but I retain a visual memory of where things were last. I look in the refrigerator to see what we have. I look at what is in the cabinets and on the counter tops. I've done this so many times (whenever I get hungry, because I want to know what there is to eat) I could pretty much recite 80% of what is in the kitchen. They on the other hand will ask me where something is when they could just open the door of the refrigerator and see it right in front of them.
Why do people do this, and what is responsible? How hard is it to observe your surroundings?
