What is that supposed to mean? That maybe sometimes our loved ones don't live long enough because we don't "need" them enough?But on a more serious note, I do think a lot of it has to do with the relationship with their owner. My cat knew I needed her. We were (and still are) very close. People would even mistakenly call me by her name vice versa.
I needed my Sonic and still do, losing him broke my heart. What you have said sounds very dodgy and almost seems to be putting the blame on the human for not being dependent enough.
Very confused, maybe I misunderstood but I found your post quite upsetting.
