LOL you guys are funny!!
i don't so much hold imaginary conversations, but i do envision really in-depth scenarios. for instance, today i was walking down the street, and i imagined a car who i had to stop for - what if i hadn't stopped walking? what if they had hit me, and i dove enough to avoid getting killed but had my leg run over, and the woman would pop out of the car, and i'd already be calling 911, and the woman would be all "you weren't looking!", and then flash forward to the courthouse where i'm presenting my case and i argue, "it's of no consequence whether i was looking or not. it makes no difference, because i had the right of way, and you did not. you must legally yield to any pedestrian. the law does not specify an attentive pedestrian. any pedestrian. moreover, even if i had been looking, it's not like that would have facilitated me escaping your car barreling towards me at speeds which really were much too fast for the corner you were taking. the fact remains that you could not have slowed down in time to not hit me, and that, ma'am, constitutes reckless driving... but all that aside, the pure fact remains that you, in a car, illegally hit me, a law-abiding pedestrian, and as such i request a sum of money to cover all medical bills for now and regarding future treatment..." and then i win the case obviously, and get tons of money, and fame, and respect, and... yeah, that's about where it ends.
it's always bizarre scenarios where i get sort of hurt but come out on top, looking like a hero.
