Back before 'Brick,' I wrote a short film that I never ended up shooting: hit men in the present who work for a mob in the future who send their victims back in time. A guy is sent his future self, he lets him run, and the whole short was them chasing each other across the city. That sat in a drawer
I think that the only way to teach is by example, as children will more easily follow what they see you do than what you tell them to do.
