OMG - what a sad song! I've had to put down pets on occasion and it still hurts to think back on those decisions. I think the hardest one was my pig Rooter. Yeah, we had to shoot him because he was causing trouble in the neighborhood. We had him butchered, but I couldn't eat him and I've not been able to eat meat since. (See my story "How I Became a Fishytarian" on p. 291 in my book.)
