It has been an intense and stressful year for those of us in the United States–elections, shootings, terror threats, high health care costs, etc.  Even more than usual, we may be looking to the holidays as an opportunity for relaxation and escape.  So I wish for each of you a very pleasant time with family, significant others, friends, pets and whatever other companions and activities you enjoy.  Take pleasure in these things and forget the rest, at least for a few days.
