There seems to be a lot of confusion about bubbles. As I understand it, and I may well have missed something, this the situation in England:
Being in a bubble means you are essentially part of the same household, so can sit close to each other, travel in the same car, sleep over in the same house and yes, cuddle the grandchildren who are part of the bubble!
Those who aren’t in a bubble can meet up with people from another household in a garden or even indoors, but are still supposed to maintain social distancing (so no cuddles).
The poor saps like me who live in the special lockdown zones and aren’t part of a bubble can only meet people from other households when they’re outside, in public spaces, keeping their social distance. Fingers crossed we’ll be let out soon.
