Many thanks all :-) Bless you guys :-) Emeritus- yes he is much better thanks. Although he is cold which is really not like him at all- he is always warm even on the coldest winter's day. We live in a warm cosy terraced house, too. Still, he will be okay as he is in the best of hands- Bea's ;-)!
My parents came around early this morning- did lots of shoopping for us + vacuumed the whole house- bless them. We are very blessed. The phone keeps ringing for Chris, too :-)! Rollo- you are a star!! Rollo- good name at this time of year ;-) too! Thanks bluesfan, too! Bless you all!
Hugs, Bea
