I’m pretty sure the guidelines are only talking about going out.... “popping out” to the shops, meet friends, play in the park, have a bbq on a farmers field is fine.
We're talking about 'essentials', but: if I want a bbq in the field attached to my home with my household (we have the landowners permission), that's ok. You might not know that I'm allowed to be there and we're all in the same household, but you aren't owed an explanation for anyone else's behaviour
Popping out to the shops is a perfectly normal turn of phrase around here - we don't differentiate with big, weekly or small shops as some MN apparently folk do - if someone's popping out to the supermarket around here you can't assume it's not essential. Once again, you aren't owed an explanation of other people's behaviour.
Playing in the park (not on equipment, as per the stated guidelines) - absolutely fine as long as you're observing social distancing, not everyone has a garden or outdoor space they can access privately, or a home that's safe to remain in all day. Still not owed an explanation for other people's behaviour.
Meeting people - not ok, but the guidelines say stick to your household. But do you know, just from looking, who is meeting because they're a carer or have other responsibilities? Something about not being owed explanations.
That's the whole problem: people don't know each other that well (if at all), so they make assumptions and judge them on that basis, not fact. Some people aren't sticking to the guidance, but it still doesn't mean that you have a right to an explanation from anyone else, or the right to judge them in its absence.
