@tunnocksreturns2019 You've been through some tough times, that's for sure. It's totally understandable that you might feel a lack of empathy for people who are whinging about stuff that seems pretty minor, by comparison. I hope things improve for you.
I think that the blitz spirit was perhaps exaggerated/romanticised by wartime propaganda and Hollywood films made afterwards, but people were probably more stoical back then, as their lives were undoubtedly much tougher in many ways than they are today. Back in 1939 most working class people lived in very basic housing, with no central heating. They didn't have freezers, automatic washing machines or microwaves, few had telephones and nobody had TVs or computers. Birth control was practically non-existent which meant that large families were common, so many houses were severely overcrowded. Most terraced houses didn't have proper bathrooms - just an outside toilet and a tin bath which had to be filled using kettles. The NHS didn't exist, many women died in childbirth, and there was little in the way of social welfare to support the poor. It was socially acceptable for naughty children to be hit by their parents, teachers, or even by the police, who would routinely clip unruly kids around the ear, just for being cheeky. All in all, life was tough in the 30s, so the people brought up back then were forged in steel.
All that said, 2020 has been a miserable and sad year for many people, and it's understandable that people feel stressed, after trying to avoid an invisible enemy for months on end. Hopefully this war will be over fairly soon, rather than drag on for 6 years.
