as Dad was putting on Will's snow boots, Will said: "mama said that it is easier if I stand up to put my boots on." Dad, recognizing that the downward force created by Will's body weight would assist the effort replied: "mama is smart, isn't she?" to which Will replied: "yes, she is, but you just make mistakes." Dad, wounded, continued to assist in getting Will dressed only to realize a few seconds later that snow pants dont fit well over boots, a sequencing error that Will instantly recognized as another "mistake".
