Observe yourself going about a normal activity, for example: riding the subway, buying a coffee, brushing your teeth, etc. Narrate your actions to yourself in second person. Later, observe someone in the world and, to yourself, narrate their actions in second person. How did the two experiences differ? Did you find yourself making assumptions about their emotional state? What was it like to describe your own actions?
