The best part of The Curious Incident of the Dog in the Night-Time by Mark Haddon:
time is not like space. And when you put something down somewhere, like a protractor or a biscuit, you can have a map in your head to tell you where you have left it, but even if you don’t have a map it will still be there because a map is a representation of things that actually exist so you can find the protractor or the biscuit again. And a timetable is a map of time, except that if you don’t have a timetable time is not there like the landing and the garden and the route to school. Because time is only the relationship between the way different things change, like the earth going round the sun and atoms vibrating and clocks ticking and day and night and waking up and going to sleep.
time is a mystery, and not even a thing, and no one has ever solved the puzzle of what time is, exactly. And so, if you get lost in time it is like being lost in a desert, except that you can’t see the desert because it is not a thing.
And this is why I like timetables, because they make sure you don’t get lost in time.
