So hear no evil,see no evil, as long as you follow the lockdown rule yourself, let your neighbor have parties , happy gathering with friends n families , if they passed the virus around only the medical staff take the risks and the burdens for NHS , so what the point to have all the isolation for not every body followed.
I really don't think that anyone is saying this, though. Parties and 'happy gatherings' (as opposed to glum ones - are they ok?) are clearly wrong - not just because they are 'against the rules' but because they are very likely to pass on the virus (if someone there is infectious).
A couple taking a car to the shops and then going into separate shops is a completely different matter, which is the point that a lot of us are trying to make, although it's not easy to convince some posters. Not only is that 'allowed', but it's not dangerous. It is no different from one person going twice, it's probably safer than walking (so long as they don't have an accident), and it halves the number of trips they need to make if they buy twice as much in one trip. What about all the people driving to click and collect? Should they be reported too?
Partying (or any large gatherings) is clearly against the spirit of lockdown, and would be unwise even if we weren't living under these rather confusing rules. How others are managing their shopping, why they choose to stay on or go out for exercise outings, or what sort of exercise they choose to take, on the other hand, are just not the same thing, and do not need to be reported, as, ultimately, they are reliant on judgement, and require a level of understanding of personal circumstances that others simply do not have.
Nobody is arguing for a completely laissez faire approach to this - just saying that the rather gleeful way that some people are willing to point the finger is unedifying and not as 'helpful' as they often pretend.
