I think with my last job working for a veterinary office, the biggest challenge is getting to attach to the pets. I have known some of these people, these clients, for nearly five years. And being, knowing these dogs and these cats, when they come in, if something happens to them, and you get attached, and you have to sit with the owner when a euthanasia comes, and you have to hold the owner's hand and be with them. And helping them say goodbye to that pet is heartbreaking, but you use your resolve, and you move on. You know, you use your compassion, your empathy. And you do your very best to make sure that they are comforted, and you just move forward and on to your next task afterwards, because the next client walking in the door after that euthanasia could very well have a brand new kitten that they're very excited to have. And you have to be professional and courteous, and put a smile back on your face, and move on with your day.
