I was chatting with my 91 year old grandfather one time in his kitchen. I poured myself a glass of milk out of his refrigerator. The milk was spoiled. I asked him why he didn't buy fresh milk, to which he replied, "I just can't afford it." He was a lifetime saver and had a lot of money, but was a child of the great depression. He didn't spend anything that wasn't completely necessary. He drank spoiled milk during the depression and saw nothing wrong with drinking spoiled milk in 2010. I knew where he kept his checkbook so I went and got it and showed him the balance. The balance was seven figures. That didn't include all of this investments. He invested very well for a long time, since the 1930s. Nothing was going to change his unwillingness to spend money, because you just never know when you might run out.
I went to the store and bought him some milk and a few other things. I dumped the spoiled milk out.
