" Listen. There is a sound like the knocking of railway trucks in a siding. That is the happy concatenation of one event following another in our lives. Knock, knock, knock. Must, must, must. Must go, must sleep, must wake, must get up — sober, merciful word which we pretend to revile, which we press tight to our hearts, without which we should be undone. How we worship that sound like the knocking together of trucks in a siding! "

― Virginia Woolf , The Waves
