He’s used to the company of animals at work, and dead ones at home.
He skinned animals for fun, stuffed them, and displayed them. It was quite a collection, if for no one’s eyes but himself.
Then he realised he accidentally brought home a live dog instead of roadkill.
It was still breathing, but it had a severe slipped disc. The vet recommended surgery, but he decided to take matters into his own hand.
He wasn’t used to company, but the whole experience left a deep impression on him, alive, or dead.
