Today, I am filled with regret. I bought a dog in my late twenties. I vowed to look after him and walk him every day. As life got more and more busy, I worked harder and harder, and the dog became less of a priory. He was still fed and let out of exercise but was no longer the focus of my attention. This evening, I came home to find the dog dead in the kitchen. I feel like I wasted his life, we should have spent more time together.
