A note about comments
Because of a glitch in the Blogger software, a few recent comments from readers have been deleted from the blog and there doesn't seem to be a way to restore them. So if you notice that a comment that you had made here is no longer visible, I just want you to know that I didn't do it! I love my readers' comments - all of them - and would never delete them. Apparently, the glitch has now been fixed and it is to be hoped that no more of your interesting comments will be dropped. Keep them coming!
