Back in 2004, I had was single, and lonely, and I pretty much hated myself. Trying to learn how to talk to people on the outside, going home alone at night and fighting depression. I got a dog.
I was on recruiting duty at the time, which means long hours, and not much money. That poor dog was there for me when I needed him, and I was not around enough to take care of him the way he deserved. I tried to give him affection when I was around, but sometimes, I was overwhelmed by life and even man's best friend couldn't get me out of my funk.
I didn't happen right away, but the dog became aggressive. Too much isolation and not enough love. He ended up biting a neighbor, and I had to put him down. the neighbor was fine, but I was never the same.
I have learned to live with the guilt, but I have never forgiven myself for that dog, who deserved so much better than I could offer him at the time. I get choked up just thinking about it, even now.
After that, I learned to try not to always be selfish. To think about other's plight and feelings. I always want to treat living beings with respect, never miss an opportunity to tell them how much they mean, and to show them the affection and attention they deserve. My username is a constant reminder of that.
That dog's name was Caesar. I owe him my life.
