The thing is, it's easy to say disregard those who break the rules and just to keep oneself safe, but the disregarders will force those of us who are shielding to be isolated for even longer if there's an upsurge in infections.
My nextdoor neighbours not only had friends round last weekend having a raucous get-together but, judging by the cars parked outside, several of them stayed the whole weekend and at least one other couple stayed the whole week.
This behaviour is very upsetting and frustrating for those of us - like me - who haven't seen grandchildren and DD since Christmas, and have only seen DS twice in a socially distanced garden visit..... in which we couldn't hear ourselves speak because of the neighbours' drunken racket from nextdoor.
