I see so many posts on social media of all kinds asking 'What do they not get?' and complaining about all the people who are out when the poster is out, but apparently shouldn't be.
I speak as one who has not been out at all since a week before the 'lockdown', so I'm not arguing for a free for all, but the answer seems clear - there is nothing that people 'don't get'. They are just interpreting the advice differently from those who see it differently from them.
I don't think it is sensible for people to flock to beaches, and there is the question of what happens if visitors' cars break down or they take ill while they are there, but at the same time, those who live near open spaces don't own those spaces, and they do afford a better chance of a socially distant walk than a city centre.
People who live in crowded areas have suffered disproportionately in this crisis, and it's all too easy for those with large gardens and access to fresh air to be judgemental.
Someone on my local FB page nearly caused uproar recently when he posted that people from the towns should not bring their children or dogs to walk through 'his' village, as he had moved there to get peace and quiet. It was pointed out (quite forcefully ) that he must do his shopping in one of those towns, as the village had no retail outlets, which is fair comment, really. The same applies to medical services, which are all in the towns, so villagers would have to drive in if necessary. You can't have it both ways.
The idea that some people should have exclusive rights to communal space on the grounds that they live nearby is fairly selfish, and it is one-sided when they also expect to visit other areas to get their own needs catered for.
Maintaining social distancing on walks is another matter, and should, of course, be adhered to by all, regardless of whether they are local or visitors.
None of this is straightforward, and a bit of give and take all round would go a long way.
