Yep, that's about how it is.
They spend most of the morning in Greece, and then head on to Egypt before nightfall, where they make a little house in a date palm. She makes it through all of her books. She gets to see the pyramids and the sphinx and Egyptian people going about their lives. She is thirty.
They head more or less straight east from Alexandria, not knowing exactly where China is. They hit India by noon, where they explore more or less randomly. It's fascinating, and moreso because she has no idea what to expect anywhere they go. They spend another night there. She makes a little wooden flute and tries to play it and laughs at how bad she is.
In the morning they hit coast and walk along it for a long time, and then a very long peninsula with an island on the end of it, and then they are in Sumatra, and then Java, and then a host of other tiny islands before there are no more islands to hop to. Borneo and Australia are both too far to attempt, and they must head back the way they came. They spend a second night in the island chain. She is thirty-five.
The fourth morning they finally find China. There's no shortage of places to explore; it's enormous, and full of fascinating people doing fascinating things. When they've gotten a sense of it he asks her where they ought to go next, and she tells him that, actually, she knows how the world is shaped now, and she's been away from her children for ten years, and she misses them terribly.
They spend a final night in China, and on the fifth day they come home.
