Wasn't the whole 'Blitz Spirit' thing a careful government propaganda campaign to get people managing through it anyway? Not that people who lived through the bombing weren't brave and resilient, but they were also human
Clearly I wasn't around during the blitz but I do remember some of the stories my Nana used to tell me.
She was one of the first female tram conductors in the country, and two of her sisters worked in a munitions factory. There was a lot of "empowering" moments, mostly for women, in the war.
Which is kinda categorically the opposite of what is happening right now.
When Dementors use that as a patronising way to tell you it's only a few weeks, imagine how they survived then, I think it's completely different? I used to work in defence manufacturing and there was always a buzz when we knew there was an operational need for our stuff. We all leaned on each other, worked around the clock, brought cakes in and ordered Dominos pizza on a night shift.
This is complete isolation of people. Categorically different.
