Me, too, Flutterby! No need to apologize.
I've been in pain for 6 wks now with-sciatica (piriformis syndrome) and a pulled hamstring. Sitting is my worst position, so I put the computer up higher and stood while I typed.
I am sitting right now but it won't last long. It never occurred to me to apologize for not being around. I guess you're just way more polite than I am!
Be good to yourself.
