"I'm a writer and I look after our little house here in this coastal rural village while my wife works and supports me.
"What I do is to write and speak and I also help other people by reading what they have written and help them improve it. The really curious might ask "What do you write and speak about?" To a nine-year-old I would reply by saying something like "Social things." That would be a platform for answering any further questions. I could probably also say that I have spent many years teaching in the university and these days I am living quietly in order to do more reading and writing. I might say that I write books."
