Its about how we can be so compassionate with our pets and yet not feel the same way towards our fellow man...
I think we feel that way because animals don't expect nothing from us except love.
Our fellow humans are not like that. Some are evil, some are manipulating, some are liars, some are thieves, some take advantage of others. Some people think about nothing but themselves.
Our pets are not like that, they love us because we take care of them.
There are a lot of things that I would do for an animal that I would not do for another human.
