The Watchman

Ernie's job was to make sure the lobsters didn't escape from the tank. He had to keep a sharp eye. Oh, they were sneaky. They would climb atop each other until the top one could climb over the edge. On several occasions Ernie had to chase after them as they sought escape.
Sometimes he tried to make eye contact. He would dance and sing for them, showing compassion. But he was warned not to get too close to any of them. The next day another shipment would replace the previous lobsters.
He had been a watchman for soft shell crabs, who were surprisingly social. He gave them hand signals and they responded by flipping over onto their backs.
There were rumors he might be placed on snail duty. Ernie dreaded the possibility. Snail were aloof. They won't make eye contact. He thinks they actually have an inferiority complex.
