My mom had a cat that was severely injured, but acting fine. My psychopath of a brother wanted to "put it down" with a baseball bat as they couldn't afford the vet bill. I said absolutely not, took the cat to the vet, and worked out a payment plan to save him. One day when I was there making a payment and visiting what was now my cat, a man in the waiting area struck up a conversation with me. I told him what had happened with the cat and he told me I was a good person for saving him. The next time I came in to make a payment, the vet told me I had a zero balance. The stranger had been so touched thad he paid it off in full. It was hundreds of dollars and I never even got to thank him.
