"No, but don't let me stop you."
Coming for a swim? What's the woman talking about? The tides out! If she's going for a swim she's a long walk ahead of her, one that will take her to the sea way beyond the Outer Zone! Mind you she could go for a swim in The Village swimming pool or lido, un-heated and forged out of stone and concrete, and one would need to be a hardy soul to go swimming in that!
