I was always at a loss as to what to do with my barbies, my brother's matchbox cars, or anything. I would usually dress my barbies, then arrange them in a certain order. Same with my kitchen toy, pots, pans, teacups, that type of thing. I would arrange them, and once I did that, I had no clue what to do. My brother's cars, I more or less learned to play properly because he told me how, and he'd show me. He was always more or less good at sharing with me or anyone else. I never was, especially if I saw someone else was disrupting the perfect order I had arranged my toys in.
I would also give my toys 'personalities', and sometimes arrange them by that, like from lazy to angry. I know it's weird, but...well, I don't know where I used to come up with that stuff. I'm not quite sure how I could tell.
