Just the presence of friends is really valuable. And after a few days, man all I wanted to talk with someone about was the Yankees, or the weather — anything else. Not just to change the subject, but because all of those everyday things all of a sudden shone brightly with renewed meaning — you re-learn the pleasure of your interests and hobbies, the things that unify you with your friends and colleagues. A change of subject can do a lot of good, when a friend senses the opportunity is right. Save the discussion of what happened for when the grieving person brings it up.
