One user—“Marigold”—became a fixed point. Marigold’s drops were always small rituals: a photo of a tea bag after steeping, a 12-word observation, a recording of a pocket watch’s tick. People started replying indirectly by dropping things next to hers: a dried chamomile, a scanned recipe for lemon cookies, a short melody in MIDI form. No public threads, no direct messages—only these quiet adjacencies. It felt like letters slid beneath a door.
