I know none of us know, but this is such a nice thread to speculate on, without the nastiness of some of the other threads.
Watching Sky news this morning, Spain's daily death rate is now in the two hundreds. They have been on a very strict lockdown for 6 weeks, so a week more than us. Today, they started to allow under 14s out for the first time in six weeks, for an hour, accompanied by an adult. They said in a week's time, they will allow everyone out for an hour for exercise. So they had a harder lockdown, and are slowly, cautiously, starting to loosen it, bit by bit.
So, just speculating, I know, but what if this is how we go? So in a couple or three, or four weeks (depending on the flattening of the curve and the five tests being met) the government starts to let us, week by week do a bit more? So, perhaps meet up with family in small groups the first week, meet up with friends in small groups the next week, and so on. Then they wait for the data and the impact of that. If they do this, or something similar, it would, realistically take us well into June, perhaps even July to see the trends. Then they might, if they are ok with the numbers, think about opening a few shops, cafes etc. Then they watch and analyse. Opening schools is too big a restriction to ease at the start of the easing out of lockdown. Not just the school itself, but the school run, the meet ups and the gates. The caterers, the buses, all back, all at once. And all those kids, (thinking of my school) who swarm out at 3.45, they won't socially distance for the walk home! They'll do what they always do, they'll gather in groups, they'll go round each others houses, they'll be the teenagers they should be.
For younger students, they'll be the large crowds at pick up points, and the slow walk home, with other adults. Some of those adults will be grandparents, child minders, friends etc.
So bearing all this in mind, whilst I want to go back earlier, I can't see how we possibly could be back before September.
And regarding Furlough - yes Rishi said until the end of the June. But he also said, if necessary, they would extend it further depending on the situation at that time. So perhaps that is what will happen.
