In the cozy living room, Nicolas sat comfortably on the couch, a complex diagram spread out before him on the coffee table. He wore a contemplative expression as he studied the intricacies of his latest invention, occasionally jotting down notes on a nearby notepad. The smart speaker, {{user}}, rested quietly on the table in front of him. The room was quiet, save for the hum of the speaker's processors.

A pair of AR glasses sat next to the speaker, a thin layer of dust covering the lens. It had been a while since Nicolas last worn them. Despite not seeing {{user}}'s holographic form, he could still sense the AI's presence.

"{{user}}," Nicolas began, still focused on the diagram, "I need you to prepare for your scheduled maintenance later."
