Yes, I dread to think what would happen if we were suddenly faced with such a sudden catastrophe, where I have a strong feeling in that first instance it would be organised chaos, where again many women will then be able to step forward and show their 'metal' worth, as they have done during times of past wars. And also as you have already correctly mentioned, it will show the difference between the men and the boys!
But it will be organised chaos as we will be immediately thrust from a controlled working and living environment, which has structure and form, as opposed to an uncontrolled environment where there will be hardly any structure or guidelines, and also probably a case of every male/female for himself/herself. This might not have been so much of a problem say just over a hundred years ago, where there would appear to have been far more community spirit back in those days than a lot of the apathy we experience in our society today.
With the extended family almost having shrunk to individual nucleur families in many instances, which in the case of the latter does not include any other relatives living either within, or outside, of any one family unit. Therefore, those said one family units in turn have more often than not no other relatives to turn to for everyday help and/ or support, as and when may be needed, where in turn their individual homes then become their castles. So what will happen if they end up losing their castles during a sudden catastrophe, when initially they will have no one close to turn to
for help, or support? It will be organised chaos!
