Another thing about lockdown is - try not to be the lockdown police. Too many people in March and April worked themselves up into a frenzy replying to anyone who mentioned long walks or similar to say how irresponsible they are and that thousands will die.
I'm not saying don't try to encourage friends to act responsibly, but last year I remember getting messages about how sitting on a bench or walking for more than 60 minutes made me a bad person.
Isolation is tough and it makes us angry when we see others not following the same rules. But there is a difference between what is law and what is recommended. And shouting at other people going through a tough time doesn't help anyone.
