Absent

I have been away for a while ... a long while. I keep thinking I'm coming back. But I don't think I am. This blog will remain here but new postings are increasingly unlikely. My thanks to people who used to read here and my apologies to those who've sent me emails over the past two years. I really haven't been on top of checking that inbox, so a number of you have probably had your queries go unanswered. Sorry.
