im pretty good at remembering where i put things, since i put them in places where its logical for them to be(logical from the perspective i am while putting it there, also i tend to put things back where i took them(for example i can tell where nearly all my spices are in about 3 cm accuracy in my spice cabinet, because i put them back exactly where i took them when using them), and i have really good episodic memory(remembering times, places, associated emotions, and other contextual knowledge), so i remember usually quite exactly where i was when i put my camera down last time(what room, what part of the room etc i was in when putting it down) and by going there i can easily notice where the item is, since its in a place that makes sense where im standing now). however, sometimes i might not remember where something is(if i have placed it somewhere without thinking about it, i put it in somewhere where it shouldnt be long time ago or am searching for scissors at mates apartment for example) and i often REALLY suck at finding things which are in unknown/illogical place. finding those things is also very frustrating and i get really annoyed fast if i dont find it fast, or have looked all over twice and simply cant find something, because my eyes simply didnt register the item when i was looking at where it is.
