Jean- no need to apologise. I don't feel you're butting in -I really appreciate your concern
I'm not too bad- had a rough time at work with an unpleasant colleague but I'm used to her now and just accept that she's the one with the problem.
I'm not at work today as my knees are bad so am resting. And I don't feel guilty even thought the weather's lovely and i'm going to sit in the garden later.
Thanks for your kind thoughts
