Jack’s hand gently glides along the handrail as he runs up the stairs to his room. The corridor is dark, but that is no problem for Jack. His home exists as a carefully mapped out place in Jacks mind. Every corner and step and doorway. Where the water is kept in the fridge and where his hot chocolate pods are kept next to the coffee machine.

Jack wanted to show me his puzzle book. One that looks similar to the activity books I had as a kid, full of mazes waiting to be solved. Except in this one the lines are tactile dots. I can’t see the booby trapped exits full of sand snakes, but Jack knows they’re there. “ohh no” he says with a chuckle as I end up there again and again. “Trace the inside walls, it’s easier that way” Jack coaches me. With my eyes closed I am trying to understand this two dimensional world with my fingertips. But I keep peeking, because I feel vulnerable without my sight. To me, not being able to see the world i’m in is scary, but for Jack it’s his reality.
