Thanks very much, Rob.
By the way, I liked the teaching method you described in your post about the man who chained his dog outside in very cold weather. Perennial forum? it might have been direct enough to get through his skull.
But you should have offered to take his coat, hat, mittens and other clothes before chaining him out there to see what it's like for the dog.!

(P.S. In NY state, we had a slightly more acceptable name for people like that, namely "putz-head". In fact, that was the nickname for one Senatorial candidate many years ago.
I think that NJ had a bad effect on NY manners, if "NY manners" is not a contradiction in terms all by itself.
