I have to share with you a magical moment that happened yesterday.

There’s an express bus service that runs past my house every 10 minutes (I know, sweet right?). Lately I’ve noticed that the bus sometimes makes an unscheduled stop a few metres before my stop, lets people off, and then moves down the road to stop again at the actual bus stop as well. I’ve only seen it happen twice, and the second time was yesterday

My housemate, who usually drives, was on the bus with me. A few metres from our stop, the bus did that thing where it mysteriously pulls over. People started leaving, so we followed them off the bus like slightly baffled sheep.

My housemate is a solid sort of person who brooks no nonsense, and she wanted to know why the bus was being so weird. I didn’t have an answer. But, I pointed out, both times I saw the bus do this, an old man with a cane disembarked at this same spot. I pointed to the old man in the woollen jumper, who was hobbling down the sidewalk. ‘That man.’

My housemate stared after him, then looked back at me, her eyes glowing with wonder in the afternoon sun.

‘Wow,’ she breathed. ‘He must be a wizard.’

Yes, a wizard. Nothing, not even expecto patronum could have impressed her as much as getting an irascible city bus driver to pull over at an unmarked stop. During peak hour, no less.

Who is this old man who can stop buses with willpower alone? We just call him the Wizard. As ancient as Dumbledore and as enigmatic as a unicorn, you never know whose bus he may embark next. It could be yours.
