From the news: A killer whale attacked and drowned a trainer at SeaWorld.
A killer whale held in captivity in a pool is sad.
The sequence of the images the trainer rubbing the whale and then the whale attacking the trainer is sad.
Somebody drowning is sad.
Sea parks and zoos are sad. Never liked them, even when I was a kid.
Theme parks, amusement parks and circuses are sad. (Oh, the irony…)
Clowns are sad. And somewhat offensive. It always seems like the exaggerated smile is hiding a vast sadness.
