@Gwenhwyfar, the laws around drug dealing etc are there for very clear reasons, that everyone agrees with. The rules around Covid, have been contradictory and the chief science offers have ok'd the breaking of the rules by Ministers, so there wasn't a reason for them, then, who knows? Whitty and Valance don't, their nodding dogs.
Advice and risks have changed, everyone needs to keep up with them.
A lot of people on here who've stated they've broken the rules and gone to help out, or needed help because of pregnancy/age etc, haven't broken the rules.
I didn't break the rules by carrying on providing childcare for my key worker DD. This was covered on the BBC.
The 'rules' were spread by Chinese Whispers (pardon the obvious pun) and few were actual guidance.
My specialist Nurse advised me that they were being cautious at the start with the shielding letters, but I'm not at particular risk. Now we know more.
For most people this will be a cold, so it's ludicrous to suggest staying at home and not having contact with people. Especially for our children.
I'm putting off doing anything outside childcare, shopping (infrequently) and having to travel on public transport. We'll see if the protests, shops opening etc causes anymore deaths, because having had serious pneumonia, just getting this doesn't scare me. We've built up a fear against a flu.
OP, make your decisions, based on your risk, but don't be so bloody selfish to suggest that because you need to shield, everyone should live as you have chosen to.
