Sam and Peg were watching other islands from a roadside lookout near the top of a mountain. They'd just finished a joint.
"Serene," she said.
"What exactly? What's the most serene?"
"Uh, the water."
"I like the islands," he said.
"Well I like the water."
"What's that water called?" He pointed.
"Umm... that's Perseverance Bay."
"How enduring."
She laughed. "And that's the Caribbean Sea, and that over there is Water Island."
"Huh. Kind of a contradiction, don't you think?"
"What?"
"Well if it were a water island, it wouldn't be an island. It'd just be more water."
"But water can be on an island," she said.
"Yeah, but if the island was water."
"But it is. There's water in it."
"But it's not all water," he said."
"No. You're right. We see the land."
"And that's water." He pointed to the bay.
"Is it?"
"It is. Trust me."
"But there's land underneath," she said.
"That we can't see."
"And islands we can't see."
"What, because they're underwater?"
"Right," she said.
"No way. An island, by definition, is a body of land surrounded by water."
"They are surrounded by water."
"Okay. Right. I mean surrounded but not completely surrounded by water."
"But if the tide went out they'd be islands."
"But they're not islands now."
"Why not?"
He looked at her sternly. "Peg."
"What if all the water was gone?" she asked.
"Then it'd be one big island."
She smiled victoriously. "Right. Let's go to my place."
