It's not about that though. It's about people mingling in large groups around a playground. They said the same in Germany, don't close playgrounds as children need to play. Then they realized that playgrounds got very crowded with children and adults mingling especially given the fact that schools were closed. Eventually they shut them down.
Yeah, a huge crowd here too, in the supermarket. No "social distancing" observed. The queue was also as long and as jam packed as ever. Didn't bother to enter the premises.
I don't know which one worries me more - the virus itself or the art of foolery (of people). Just let the masks go extinct and not a single soul will dare to venture out of the door.
"Masked" psychology and mentality.
