I have a daughter in good health and no pets at this time. I have had pets and I have had to have a couple of them put down when the only other option was to let them suffer. I'm pretty lucky. And I think they were lucky.
The family member who inspired this thread is an almost-40, never married, lives alone, single guy with no kids. Since he has never had any human family members, he has nothing to compare with. So this is likely very big IN HIS LIFE, but it strikes me as a bit melodramatic.
I'm pretty sure that animal owners who have no children and parents who have no pets see this issue differently.
So I asked my BFF, an animal lover who has had to put several animals down over her 75 years but has also had to bury two human children. She tells me there is no comparison.
I know that people who don't have kids...my pushing 40 years old daughter whose rescued kitten is getting old is among them...feel that losing a pet is the end of the world. But people who have been through that experience AND the loss of a child tend to see these losses as distinct events. And, from my recent perspective, opting to NOT have my mom's broken hip repaired and increasing her meds for pain relief KNOWING that her cardiopulmonary response would not handle that choice was far more difficult a day than relieving a pet's pain.
I'm not saying the guy wasn't legitimately suffering...but if this is the worst day in his life...he's one lucky dude.
(Okay...I'm a cynical old bitch because another friend recently witnessed her 42-year-old son decide to unplug...amyloidosis...and he said, "Let it be," and he was gone in a few minutes...after 76 days on life support...leaving a wife and two kids. To me, THAT'S the stuff of "the worst day" in someone's life.)
