All children have to be deceived if they are to grow up without trauma.
When you become a parent, or a teacher, you turn into a manager of this whole system. You become the person controlling the bubble of innocence around a child, regulating it.
After all, when we were children, when things went wrong, there wasn’t much we could do to help put it right. But now we’re adults, now we can. That’s the thing, you see? Look at us, Akira. After all this time, we can finally put things right. Remember, old chap, how we used to play those games? Over and over? How we used to pretend we were detectives searching for my father? Now we’re grown, we can at last put things right.
