you stopped taking these routes when the buses changed, when the job moved, when the canal path was closed for works that never reopened. they are not unwalkable; you simply no longer have reasons to walk them.

they live now as a private map laid over the public one. the bakery is still there. you suspect the chair has been sold. there is a particular junction where you used to pause out of habit, and you do still pause there, in the imagined version of the city, when you are stuck on a sentence.

a route does not require you to keep walking it. it requires only that, when somebody else describes it, you correct them with the certainty of a custodian.
