1. Late one night, a delivery driver pulled up outside Little Smiles dental clinic. The street was quiet except for an odd humming sound coming from inside—a tune so sweet and persistent it almost seemed like someone was whistling. Curious, he peered through the window and saw only a tiny light glowing softly in the back room. Inside, amidst the usual instruments, sat a small, smiling figure humming away. ‘Hello?’ said the driver gently. A little voice replied, ‘Just polishing my teeth, thanks for asking!’ Turned out it was just the dentist’s new helper—a friendly neighborhood hamster.’
