I stand by the fact that the attitude of people on mumsnet is a lot more grave than the people I'm in contact with in real life, in Facebook, or on the news.
People in your bubble have a certain attitude. That's not necessarily reflective of the rest of the world. We have had a lot of talk in recent years about how social media echo chambers can distort things and give us false impressions of the world.
We've already established that you don't pay huge attention to the news because you don't understand what the guidelines are.
And then you post this:
It would be the mass social gathering, particular with strangers, that they feel is covered under government advice. However, on here, I shouldn't have friends or family over, apart from, I guess when I pick my daughter up for the weekend. Try convincing my mum not to pop in for mothers day, ther is just no way, she'll be coming no matter what I day. But according to this thread that would be breaking official advice?!
Which rather illustrates the point.
Yes they mean all non essential social contact including with family who do not live in the same household as you.
Johnson said in his speech
"Now is the time for everyone to stop non-essential contact with others and to stop all unnecessary travel."
It is not essential to celebrate mothers day.
All fun is cancelled until further notice. That's ENTIRELY the point.
