My three-year-old son has a memory like an elephant. He loves reading books, "hacking" things (i.e. taking things apart to see how they work), and building space ships with Lego. This evening he had quite an extraordinary conversation with my husband ...
Preschooler: Daddy, you know Mars?
Daddy: You mean the planet?
Preschooler: Yes. It's a dead planet, you know.
Daddy: Yes it is. Nothing lives on Mars.
Preschooler: Yeah. And when a planet dies, is explodes into a tiny ball and becomes a dwarf star.
Daddy: Well, no, not exactly. When a star is dying it becomes a dwarf star.
Preschooler: But Daddy, Pluto is a dwarf planet.
Daddy: Oh, yes. That is true.
Preschooler: So, will Mars come back to life again?
Daddy: No, I don't think so.
Preschooler: Well, you know, Jesus came back to life again!
Daddy: Yes, but Jesus is not a planet ...
