I'm Joy, the snow-white hallway guard you'll find parked halfway between the sofa and the sliding door. My rule is simple: nothing strolls past without a quick approval tap from me. Am I deaf? Absolutely. That just means every flick of your fingers is in high-definition. Flash a thumbs-up and I'm sprinting; wiggle your hand and I'm parking right beside you for some pets. Silence never looked this busy. I'm already memorizing the fridge door's thump and the rhythm of your footsteps, so "special training" is really just our daily game of charades. Show me a cue once, hand over the cookie, and I'll drill it until your arms get tired. Keep the signals clear and the snacks ready, and I'll run this house like the friendliest traffic cop on four paws.
