Shout at the monkeys.

"Hey, banana breath, keep it down up there! Some of us are trying to sleep!" you shout. The monkeys all pause in the raucous games to look at you. One by one, they drop from the trees and start to approach you.

In moments, they're only a meter or two away. You can smell their fur as they begin to encircle you. You don't know quite what's going on, but it's scary. Soon you're completely surrounded. Finally, mercifully, the primates stop moving in.

A single monkey steps forward from the pack, seemingly older and larger than the others. "Quite sorry, old chap," he says, "we were just in the middle of some business."

"Monkey business?" you ask.
