Many thanks for doing the spadework. Our daughter has just informed us that we have two extras for Christmas dinner who are doing the same on-call shifts as she is- one Omani muslim and an Indian vegetarian Double pigs in blankets all round. I've been told my next task is not to do a 'Duke of Edinburgh' Merry Christmas everyone. Hah, send them down to us, I'm making a warm-spiced nut roast, wrapped in plaited puff pastry, even as I write! I take it she's a health professional? They are all doctors. Best call of the season. Resuscitation on tap while we keep on drinking and they can't. Perfect, you can always get a lift into work, if you come over a little strange 'er' ! Never envied a medic...ever! Have a good one !
