It appears to me it's an age demographic thing, I know I have one son who is extremely cavalier and appeared to think a week or so ago we are out of the woods. He turns up every few days and sits in the garden having arguments, not heated ones, to that effect, although there isn't a great clarity in the guidance, but one has to keep oneself up dated because the situation can change daily. My other son, keeps himself better informed is much more considered in his outlook and both he and his girlfriend would observe the distancing measures when out and and about that both sets of parents are sticking to. We've seen our younger grandchildren and had them both in the house and garden. My husband's older grown up grandchildren, again we've seen less of because they've also been out all over the place in the cut and thrust of protest marches and the like.
Having said that, I think this is easier for us of the retired generation, in many ways it must be hellish for younger people, worried about work in particular and of course all this is unprecedented, I'm sure I'd have been climbing the wall back in my younger years. Aside from all the obvious worries about work and money casting my mind back there's a palpable impatience that often goes with youth to get out there and experience it all, socialising, holidays, it kind of goes with the territory, I guess stoicism kicks in the later years. We've all had time to ponder and I realise so many things I once embraced, so called retail therapy, mean very little to me anymore, I'd rather look at trees 
I remember on one of our first walks during early lockdown, the days of 1 hour exercise only and strict social distancing, seeing a group of boys in our park with balls and bikes and no concept of social distancing. I said to my husband, how hellish it must be for their parents, would ours of taken any notice whatsoever, they'd have just seen it as a great opportunity not to be at school and to be out with a group of friends on skateboards, roller blades, football whatever, I don't envy the parents of that age group.
