Must've missed those threads RTJ. For my part, I've never seen you as anything but polite and considerate - something your apology reinforces.  Many of us have behaved badly at least on occasion with far less reason than chronic pain. I try to remember not to take anything that goes on here too seriously. Most of the folks who clash would probably get along swimmingly in real life. OK, there might be a few 'accidental' drownings :-)
