Road of Evil Numbers

There's an advert on telly at the moment, I can't remember which car it's advertising - a car drives along a road and the tarmac is made of numbers.
I find this rather haunting. That was what my world looked like. Everything created of numbers.

I remember walking along the pavement and the numbers consistently shouted in my head. I had to stand on a pavement slab a certain way and at a certain number. Drains, cracks and pavement edging were my enemy!

If I didn't get the right number at the right point on the pavement or road, I would be filled with feeling bad, that evil feeling that would punish me.

There are more memories but at the moment pain is winning and I can't think straight.
