Time, as we know it, is a dimension we experience only in one direction.
If you mix the mash of potatoes and the sauce, you can't separate them later - it's forever. The smoke comes out of daddy's cigarettes but never goes back in. We cannot go back. That's why it's hard to choose - you have to make the right choice. As long as you don't choose, everything remains possible.

Life is a playground or nothing.
