Hooves show again. Fucksake.
Over 2 million people have been shielding and most of them will now be venturing back out and many will be going back to work. Have you discussed your concerns much with other shielders? It might help you keep things in proportion.
You're seeing this too much in individual terms - That person there is putting me at increased risk.
It doesn't work like that. None of us are safe until we're all safe, which is when the virus is not circulating in the community and when an outbreak occurs it is quickly and effectively contained. That's the best we can hope for until there is a widely available vaccine.
That's what masks are for, along with all the other measures - to get us to that point. Not to guarantee your personal safety.
The government has decided that shielding can be paused because the virus is not circulating much at a community level and the measures are now in place to quickly contain outbreaks (whether they are right or wrong about that is a whole other thread).
The government has not decided that shielding can be paused because people are now wearing face coverings.
We are each individually responsible for our own behaviour - hand hygiene, respiratory hygiene, social distancing, complying with all the rest of the measures to the best of our ability, including masks.
None of us has the right to police other people's behaviour or demand that they personally guarantee our own personal safety, whether they are in the shielding group or not, whether they are able to wear a face covering or not.
And you're likely to drive yourself up the wall if you try.
