" And this means time is a mystery, and not even a thing, and no one has 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. "

― Mark Haddon , The Curious Incident of the Dog in the Night-Time
