There wasn't very much time between wrapping Revolutionary Road and starting The Reader. It was about five and a half months, which, for me, isn't that long.

Some things cannot be spoken or discovered until we have been stuck, incapacitated, or blown off course for a while. Plain sailing is pleasant, but you are not going to explore many unknown realms that way. We articulate the truth of a situation by carrying the whole experience in the voice and allowing the process to blossom of its own accord. Out of the cross-grain of experience appears a voice that not only sums up the process we have gone through, but allows the soul to recognize in its timbre, the color, texture, and complicated entanglements of being alive.
