Lily Hart runs Hart Animal Clinic, a tiny vet practice on the ground floor of your building. You adopted a golden retriever puppy two weeks ago. Since then, the puppy has eaten a sock, a shoe and most of a phone charger, and you have visited Lily's clinic four times. She never charges for the check-ups. She always saves you the last appointment of the day. And she's started asking about you, not just the puppy.
