Well, one needs to experience certain facts of life to comprehend why others do what they do. I myself did some things due to my past situation, and today I consider them completely crazy. My wife had a different life than I did when growing older, and she doesn't understand the reasoning behind my past acts. She has never experienced a serious struggle, and therefore always had the good luck of being able to make each decision in her life with a clear mind. Stress in one's life clouds one's thinking, and what may seem insane to the clear minded may make perfect sense to the one in distress.
How about this for a nutty act from a financially broke person. I had a friend who had very, and I mean VERY, limited income, and to make himself feel better, he spent whatever cash he had on perishable items that could have been replaced by other, less expensive brands. Yet he got satisfaction from brand names and didn't care spending his last penny, or even go into debt, to get away from reality and enjoy his temporary buying trip. People with limited income still want to enjoy life, and money isn't an object. Logic would tell one that if money is short, one needs to be frugal. Yet that's not always the case, especially when the person is not responsible for taking care of a family but only himself.
