My thoughts today go back to Sydney, to that wonderful bright city I visited seven years ago. Of course, I know as much about this as anyone else, but it appears that the siege there has now come to an end. I was shocked to learn of it when I turned the computer on this morning – I immediately contacted my friend Darryl, who lives in Adelaide: naturally he knew about as much as I did. This is a very worrying event, and what it means I know not; but given that this gunman, lone though he seems to have been, appears to have aligned himself to so-called Islamic State, this may be a sign of something much wider and more violent. That is truly worrying, yet that aside, tonight my memories go back to a city I love – it is truly heartbreaking to see such horrific violence there.
