It seems obvious to me. We should all be carrying this fact in our heads, solid as lead, to nod at once in a while if we stop suddenly in the kitchen clutching an unnecessary plate in our hands. There was a time in this city when grief welled greater than reason and there were masses gathering in halls to contact the dead.
I don't know how they carried the burden of uncertainty in tandem with the washing. I don't know how they swept floors and darned socks while all the men were missing and everywhere seemed empty. Growing sons should not be a source of fear but as they came of age they left on boats by the thousand. It was easier to feed a mouth than a memory until spiritualism came to Sydney.
I'm not saying I want to start contacting the departed but let's think about this and maybe try a little experiment. I'll keep you posted.
