It's a horrible tragedy, the SeaWorld orca that drowned its trainer. Somewhere along the way, we've lost sight of orcas as hefty sentient beings with minds of their own and need to be respected in their own right. Which is why I feel weird visiting marine parks and didn't want to swim with dolphins in Hawaii. It must be a form of Disneyfication -- to think that dolphins are friendly, because they have smiley upturned jawlines; and sharks are nasty, because they have rows of sharp teeth.
I live with two dogs and I don't forget that they are really two wolves in my parlour -- even if they look so cute when snoring across the sofa that they're instantly forgiven. Which is why I disagree with L when he picks up and cuddles the one that looks like a teddy bear whenever the cuteness factor so impels him. If any pet owner hasn't been biten or scratched, it is because their dogs and cats have shown great restrain. Even a chihuahua is capable of taking off a finger, if it really wanted to. Maybe they should, everytime they're stuffed into a handbag. Teach us some respect.
Rupert's the sweetest natured dog I've ever had, but those teeth can do a lot of damage -- if it occurred to him.
