I think most people are using their own “Cummings common sense” rules and don’t know or care about the government’s ever changing rules, which are unenforced.
My rules would be-
Mask wearing and social distancing on transport and in shops should be strictly enforced = no mask worn correctly = no travel or entry to shop.
2 households should be allowed to meet once a week indoors or outdoors.
Schools and pubs should stay open with staggered opening times decided locally..
Limited numbers of socially distanced spectators allowed at sports and small entertainments, (no reason why people can’t attend a lower league football match sitting outside spaced out, wearing masks , or a classical music concert in a cathedral, where they can easily distance . )
Only students studying subjects with large practical element - medicine, science, music etc need be present at university, those studying English, history etc should stay at home and study remotely.
Nightingale hospitals used for covid patients, other hospitals to deal with outpatients, and other services( obviously funding/ staffing crucial for this one) . Covid free smaller hospitals for cancer, heart patients etc( this is happening in many areas).
Still, you can bet the government are bound to mess it up with yet another changed complicated system which even they won’t adhere to. Wonder what the next 3 word slogan will be.
