Sure, I’d break it into three parts. First, define a small interface for each appliance: a method to receive a command, a method to emit a response, and a state machine for the current mood. Second, build a lightweight event bus—something like a local MQTT broker or even a simple Python pub/sub module—so the appliances can listen for “story‑time” events and push back their jokes or verses. Third, write a high‑level orchestrator that reads a script file (JSON or YAML) describing the scene, schedules the appliances to trigger at the right times, and collects their output to stream to the user or a display. This keeps the logic modular, the code readable, and makes it easy to swap in new appliances or add more complex dialogues later.
