Honestly, teens are mixing as normal already. No social distancing whatsoever. If there is a local spike we all need to take action accordingly.
I've been to various shops (John Lewis being one) where till staff are wearing visors but everyone else is unmasked (which seems ridiculous when customers have to wear a mask...). Restaurants / coffee shops are packed.
Staff (and students for that matter) should be allowed to wear a visor if they want to (no obligation) and we all need to get back to normal.
My local Facebook group is full of people apoplectic that they saw someone in the coop not wearing a mask. The levels of anxiety are not proportionate to current levels of infection (people should be wearing a mask of course - it is interesting that those claiming to have a disability preventing them are often more vulnerable).
My own father, 81, slightly over weight and with a predisposition to pneumonia told me he didn't have to wear a mask going into the shops (that he shouldn't really be going to anyhow, but has decided to actually live his life rather than staying locked in the house). I told him he was mental as he needed to take more precautions due to being more vulnerable. He wore the mask. He was no more uncomfortable than me.
The best thing we can all do is sign up to track and trace and report how you are feeling everyday. I don't like the fact they are collecting so much data on us but I also want to have a real life that isn't confined to my home. I want my children to mix with friends. I want them to get an immersive education. I don't want our economy to tank so badly that we are all skint for the next 20 years.
A friend is a head in a primary school. Her governors talk endlessly about corporate manslaughter. It's not helpful. Corona is here to stay for the time being at least.
