A low pretend bridge picture · separate next teaching

Complete unrelated fiction: Original unrelated fiction. An existing-fold broad paper picture begins flat. A helper presses at its fold; it bends during contact and rests as a low V after release. No weight, real crossing or later stability is tested.

Own invitation: Show the three moments without adding a later return.

Teaching: Read before/during/after slowly. Ask for a drawing, sign or spoken turn per moment. Revisit after release separately from a later unseen moment.

Observable meaning: Sequence retains flat, bending during, low-V rest after; no real structure safety or spontaneous return is inferred.

This account is separate from held B-first-1. Offer only the wanted actual next learning opportunity, record the help/actor/exposure, and do not invent an observed response or later improvement.
