Tim McGraw song.  I always loved it, but it came home and smacked me around the head very suddenly last week when we discovered my wife had breast cancer. 

Things have moved unbelievably swiftly since then, and our outlook is  currently excellent, but as everyone else who had been there before had told me,  I experienced a shift in values and priorities.
