I thought I was beginning to look up again, when an acquaintance make a comment that she'd just written a book called the Loneliest Places, short but beautiful essays all written after her son had killed himself.  She's quite a bit like me in that we travel to unknown places when depression or grief overwhelm us.  

When I see her again, should I tell her that her boon really affected me?  I want to and she lives so close.  I don't want to break her shell. Maybe a letter would be better.
