This whole thing is utter madness. It hasn't been phased in properly, and even if some people think Boris' statement was clear, it has actually been said in a clear way so some people really don't understand what is expected of them. There are also conflicting messages from MPs, as well as differences between Wales, Scotland, England....
Generally I'm all for giving Boris some slack given that were in "unprecedented times" but even I think this is nonsense.
I would have thought that, at this stage, Stay at Home when you can should be a starting point. We should have been able to go out to exercise more than once, more parks open, keep social distancing, see family members but perhaps outside at first and still distant. Slowly seeing family a bit more but still not merging households until a bit later on.
After that, opening more larger places such as garden centres, and larger workplaces like large building sites, big offices with some clear guidelines about deep cleaning and distancing. Also more people allowed at funerals if spaced apart and outdoors, ditto weddings. Churches very carefully opened like abroad, with no singing and so on...
Alongside this should be a slow build-up of more public transport and smaller workplaces, such as small offices (perhaps staff doing alternative days at first), coffee shops where people can be limited and/or sit outside and so on. Over the next few weeks it could lead to a gradual build up of more and more going to work, giving time for workplaces to get to grips with social distancing and proper deep cleaning before staff start. A slower start would also mean that monitoring of cases (in case of a second spike) could be done more easily....
Only after all that should schools be thinking of going back, and staged as it appears they will be. Not until late summer for places where people congregate such as pubs and clubs, I think we might have to accept that large gatherings need to be limited for some while.
