I'd like to be under the sea

"So what's it like living under the sea, then?" I asked Roger. He shrugged (that is to say, he moved his relatively tiny fins up and down in a flutter).
"Oh, I don't know," he said. "Hectic. Stressful. Sometimes I feel like getting away from it all, you know what I mean?"
"Yeah." We both floated around in the deep blue water for a while.
"Hey, but at least you get to eat a lot of seafood. That's healthy," I said.
"True," Roger said. "I try to keep up my strength. You know, being the alpha male of this lot." We had at least five or six female whales quietly floating up to us.
"I see. They keep you busy then?" I said.
"Well, you know...Some of them can be right cows, but they're allright, at least for the mating season."
"Ah." I knew Roger, like all other male sperm whales, tended to wander around on his own when it wasn't mating season.
"They don't really help me get giant squid. I have to get that on my own, 'cos they give theirs to the kids over there." He nodded towards the direction of the blue-grey calves swimming closely next to their mums. "I normally prefer listening to music," Roger continued. "You know, classical music."
"I listen to classical music too, sometimes," I said.
"Yeah?"
"Yeah. Sometimes. Opera." I felt a bit silly admitting to liking opera to Roger. I should have known what his reaction would be like.
"Oh, I don't know about opera. Some people like opera, but I think I'm more of a chamber music bloke." Roger said, a bit less effusively.
"Yes, chamber music can be good."
"But not Mahler."
"Perhaps not." I tried to remember whether I had listened to Mahler outside of school.
"So are you going to South America this season?" Roger said.
"Er, I don't know, should I be?" I asked.
"Yes. Everyone who is everyone is going to South America," Roger said.
"Maybe I shouldn't go then - sounds like it'll be quite a crowd," I said. Roger chuckled.
"You're a smart one," he said. "I'm not going to South America this time."
"Why, have you found a nice little place all to yourself?" I asked. He nodded, his little eyes glowing.
"It's a secret of my own," he said.
