The seals stupidly dive off rocks into swirling black water, barking mindlessly. The zookeepers feed them dead fish. A crowd gathers around the tank, mostly adults, a few accompanied by children. On the seals' tank a plaque warns: COINS CAN KILL——IF SWALLOWED, COINS CAN LODGE IN AN ANIMAL'S STOMACH AND CAUSE ULCERS, INFECTIONS AND DEATH. DO NOT THROW COINS IN THE POOL. So what do I do? Toss a handful of change into the tank when none of the zookeepers are watching. It's not the seals I hate——it's the audience's enjoyment of them that bothers me.
