I am currently on two cancer email update lists, neither one a close friend. Am I supposed to respond to these updates which arrive every week or so? Always? Occasionally? Am I a boor if I never do? One person I see once a year; the other person I run into fairly regularly, and it is generally easy to tell, in person, whether I should say something or not (though I'm not quite sure why).
A dear old friend who lives across the country and whom I see every few years sent a mass email today announcing that her father died last night. He lived on the other side of the world, but I have very fond memories of a good chunk of time I spent with them, long ago. I responded immediately to her email, with some of those memories, my sorrow, my regards to her mother. Do I still send a note (i.e. on paper)?
