The advice to CEV was also to mix the minimum extent, from DoH
"CEV people are reminded to consider very carefully any plans for a Christmas Bubble over the festive period. Unfortunately you remain extremely vulnerable to this virus and the safest options is not to form a Christmas bubble and avoid attending shops, pharmacies and hospitality settings unless absolutely necessary"
It was never a green light 'OK to do this'
I have a CEV person in the household, and my DMum is also CEV. We were wondering about a one day Christmas visit, but as the limits of the bubbling for the 'normal' population narrowed, we called it off. (I've just seen her, for the first time since last autumn - good job she has a nice garden, wouid have been too cold for her outside at Xmas though)
It really is shit being CEV. But IMO, we were always told that Christmas mixing was inadvisable. It was never outright banned though.
So I suppose we could have been definitely excluded all along. Even though I don't remember the messaging being unclear. And I do agree that everyone knew there was going to be a last minute update - so even if one person in the group missed it, it's hard to believe they all did.
This is the human face of what 'Christmas mixing will lead to deaths' looks like. Poor family
