I am also a teacher and teach small children. If I saw any of the parents from my class flagrantly breaking the rules and posting it online, my respect for them would vanish as they clearly don’t care for my wellbeing or the wellbeing of the children in my class. I have no choice but to go to work in 2 weeks with no mask and probably little social distancing. The risk can be minimised if people follow the rules in their personal life. It’s not black and white like if you can’t distance in one respect you should just do whatever you like, unnecessary contact should not be happening. Yes go for a meal, yes get the train, yes go to the pub if that’s what you want to do, but follow the social distancing rules to minimise risk for everyone.
Also nobody is saying don’t meet up with people, you can do that without pushing your faces together. I met with a friend last week and I managed not to put my face on her face, it’s not hard.
