My garden backs into a 2 story block of flats. Very nice tenants never had any trouble but not one of them understands self isolating. All the tenants seem to be very close as they have all lived there for a long time. They are all currently outside sat on picnic benches, very close together. A mix of 70+ Year olds and then people who have invited grandchildren over. I know this doesn’t affect me directly but out NHS can not take anymore strain from the stupidity of others. Is there anyone we can report this to? I don’t want to clog up emergency lines obviously.
