I'm sad to say goodbye to my horse, but happy it's going to a glue factory.
Why would you be happy that your horse is being sent to a glue factory? You do realize they're going to kill it right?
I have no use for him anymore so it's fine.
It's pretty disgusting that you would be happy about sending your pet off to die at a factory. You shouldn't be doing that in the first place and being happy about it is worse.
If I don't need him anymore I have the right to do whatever I want. WHAT FUCKING RIGHTS?
While you might not have any use for the horse anymore, that horse still has the capacity to enjoy life and feel pain. It is not right to celebrate the death of any creature, especially one that you had a close relationship with.
