I think the home population were as 'shell-shocked' at the end of the war as those who fought it. Many had lost family members, and like the returning troops had seen all their hopes and plans destroyed and just wanted to block out the stress and strain they had suffered and look to the future because the past was too painful.
I think many soldiers felt like that too, which was why so few wanted to talk about their experiences in the war immediately afterwards and many not for decades.
My DGM, as well as losing her husband, brother and BiL in the war, also lost her baby son, born September 1914, died March 1915. Her brother and BiL were killed a few months later.
She was left alone, the only support of 2 small children, an elderly mother and an invalid sister, with just a small pension. She clearly destroyed all photos of those who died, as none now exist, although we have photos of her and her children and did not talk to her daughters about their father.
I think that the only way she could carry on as valiantly as she did, earning enough money to support her dependents, getting her daughters the good education that enabled them to make their own way in the world, was by putting the past behind her and only looking forward.
