My wife Jeanne Safer, a psychotherapist and author of four books (and veteran of a number of NR dinners and cruises), is seeking interview subjects for book number five: a study of sibling conflicts in adulthood in which the problematic sibling is difficult but has no major mental or physical disability or addiction. Interviews are in-depth and take about an hour. E-mail Jeanne at Jeanne@JeanneSaferPhd.com.
