He is sad about his dog still and about his own mental health which makes him wish his dog, three months after his death, had lived to 18 years old instead of  17. Such irrational pains and sadness.

But I firmly believe that most of our sadnesses and pains are due to a misunderstanding of the laws of the universe or not accepting them, these simple but necessary laws to our world.

We are sentience on earth and for this reason, will always die each lifetime. I wish you all the rejoice when your lovely pets die of old age. Whiskey one day just stopped. And was euthanised 24 hours later. At close to 17 years old (minus 2 months).
