You're not the only one - I have precious little family, and we decided a month or two ago to knock Xmas on the head this year. My mum lives up the road in a Tier 2 (We are tier 3) and will just be coming for dinner, nap in front of the telly, sherry, and then be bussed back home by yours truly. My sister's family (BIL+2 under 10 Nephews) are in Kingston upon Thames and are just going to be doing their own thing. We will do a Video call to them on Xmas day to see the little faces light up when they open their presents, and their parents faces fall when they see what we (or granny - she has form for this also, as she bought the youngest a hammer and screwdriver set last year - he's only 5, and she even included some nails and a few bits of wood) have got them.
The new variant is very quick to spread, and we need to nip that in the bud though. Get the vaccine program going properly and cover off the groups that represent 95% of the people most at risk. Then the rest of us can be dosed as required.
