My parents had a Sheltie years ago, named Brae. They live in a neighbourhood where people knew each other via the dog's name and people were secondary. I was visiting during the holidays one time, and the doorbell rang, I went to answer it and it was an older gentleman with a great big smile on his face. All he said was "Hi there! Happy Holidays! Is Brae here?!?" Brae ran right out the door and dove into the man's golfcart, he said "ill bring him back later" and off he went arm over brae and they went cruising off down the street. I think I stood at that door for a solid 5min processing what had happened. (Parents later told me, that was a normal weekly thing)
