I don't understand it. In the winter, when it's cold outside, we keep our house heated well. It will be at least 70 degrees inside and maybe just a little more at times. My wife wears socks, bedroom slippers and dresses warmly inside the house BUT when we go to bed, she always has cold feet and she thinks it is my duty to allow her to put her cold feet on me so they will warm up. What's up with this? Are all wives like this or is mine just defective?
