tiencvu, I'm aware that was a very sarcastic question but I'm going to answer it extremely seriously.
When one of my fish die I take it extremely seriously. I don't just flush it or bring it to the fish store and get another one. There not the same, every fish has their own personaltiy. BUt you must understand that I feel that humans, fish, ants, aligators, the works are the same though one aspect. WE are alive. Now look at it like I do.
Every person on this planet shares one thing in common, it's the mind. Every animal has that too. THus, by taking away a single life your taking away that mind, just like you dying. NOw are you afraid of dying? Well I'm sure and positive the fish are afraid too. Now if you are willing to just kill off a fish than I would bea fraid to walk next to you in a street because then there is no stopping you from killing me off.
I'm trying not to sound to, dramatic let's say, but it's the only way i can explain what i'm trying to say.
I hope this makes things a bit clearer... i see every pet big and small as the same, just like a child. And yes, when a fish dies i do get upset... but no i don't cry all day but i do mourn...
