Both sons have pointed out that if they and their healthy children acquire this virus, they are likely only to have mild symptoms or even not notice at all. They could, however, be carrying the thing, and unwittingly pass it on to me and DH. And the stats are heavily weighted against the over 70s.
So we have agreed together that our usual child care responsibilities are suspended sor now (big sad sigh) and we have bought wallpaper, paint, compost, seeds, wood etc for all those projects which we have Long promised ourselves.
(I'm very sad though...grandkids will be brought here to wave and shout to us from the safety of the car!)
