Embodied Simulation: A Shoulder in the Transfer Corridor

8:30 a.m. on a Monday, the transfer corridor at Sindorim Station. You cross the crowd coming the other way, and at the stairway entrance the corridor's width halves. You are the 'right shoulder' of an office worker walking through this crowd. Not the eyes — the shoulder. You sense the world not by what is seen but by what touches, presses, and twists you.

Become that right shoulder and describe, in first-person bodily sensation (brushing, pressure, rotation, deceleration and acceleration, the tug of a bag strap), the process from the corridor entrance, through the stairs, to coming to a stop on the platform. After finishing, add 1 'insight about this corridor's crowd flow' that can be sensed only from the shoulder's viewpoint.
