For what it's worth, my children write letters. And by "write letters," I mean "produce artifacts filled with a combination of mediums: words, paint, markers, stamps, cut-outs, quotes, etc." They understand conveyance better than I ever have, despite being a professional information-handler. I think letters are both more and less than described here.
