Practical invitation: Offer an optional real willing reception of one actual own message.
Free setup: Existing broad paper/board, one familiar suitable tool, exact description and usual communication. Agree any helper's participation and attribute physical operations. One wanted part is enough; other components may wait.
Make it happen in useful small parts
Maker chooses actual work, privacy and permitted access route.
Ask a real suitable recipient's willingness; present only if both agree.
If feedback is wanted, receive actual response or NONE; maker keeps final choice.
Full no-print/access route: Use a reachable described broad area and have a willing helper follow only accepted creative directions, or keep an accurately named unmade plan. No body/sound/writing/sensory performance requirement.
Keep the claim precise: No public exhibition, surprise, names, recording or positivity requirement.
Teacher/parent note if useful: Actual presentation/recipient/access separate from permission, plan and response. No public pupil identifier, score or response return. Missing events are unavailable, not invented.
Optional finish: Keep, change, continue another day, erase only with agreement, or stop. A source or real recipient is optional and needs actual rights/suitability/consent when used.
