The starting point and the ending point are nothing but two arbitrary choices. You make them as in soccer games, where they chose that it's 90 minutes, not less and not more. But the choices are the responsibility of the filmmaker. You have to choose to join the story at an arbitrary point, and you leave it at an arbitrary point.
Abbas KiarostamiWhen I met Akira Kurosawa in Japan, one question he asked me was, "How did you actually make the children act the way they do? I do have children in my films but I find that I reduce and reduce their presence until I have to get rid of them because there's no way that I can direct them." My own thought is that one is very grand, like an emperor on a horse, and it's very hard for a child to relate to that. In order to be able to cooperate with a child, you have to come down to below their level in order to communicate with them.
Abbas KiarostamiAll the different nations in the world, despite their differences of appearance and religion and language and way of life, still have one thing in common, and that is what's inside of all of us. If we X-rayed the insides of different human beings, we wouldn't be able to tell from those X-rays what the person's language or background or race is.
