It’s a dog’s life
Making judgments about other people’s chosen careers is a pretty stinky thing to do. Sure, you might want your nephew to be an architect rather than a game designer, but the fact is we need all sorts of professions to keep the world going round. So it’s pretty sweet when you can throw a judgmental comment in someone’s face.
It seems like even after 4 years the payback was worth it for this guy. Fido was obviously grateful for his years of education and training, and this narrowminded dog owner would have had a job persuading a “real” MD to look after him. I do hope the vet reminded her of her comments.
