From the moment we're born, we start running.
Not running in the physical sense, but we enter that great big marathon called 'life', and at any moment we can stumble, breakdown, or fall right off the track.
We do our best to ignore and forget that that's all life is – a great long track, and we do our best to forget that ticking thought in the back of our minds – just where does my sprint end?
Sometimes it's hard, sometimes it's like there's nothing you would like to do more than give up; than stop running around a pointless track that you don't even remember starting in the first place.
Some give up. Some tracks are blocked off unexpectedly.
As Harry slipped out of Hogwarts Great Hall, he couldn't help wondering.
