I don't know whether it is poor spatial awareness, poor balance, or just a love of tactile sensation, but I feel the walls when I walk.
As a child I would run my hand along the fence, rat-a-tat-tat, on my way home. I did the same with the walls, but they made a less interesting sound. I did the same with a Yucca, and cut my hands.
My trailing hand feels the path.
I didn't learn a lesson from that yucca experience and today my hands still follow walls, radiators, window panes, wood. I know where I have been from the textures on the walls I pass.
Texture, balance, whatever. I feel my way wherever I go.
(Not sure if that's just me, and an odd compulsion that is all my own, or a perfectly normal behaviour that I have just chosen to vocalise.)
