When parents pass away, family dynamics can change. Usually a family can weather what Marjory Levitt, an associate professor in Temple's department of psychological, organizational and leadership studies in education, calls a "development arc in sibling relationships." "There is no one resolution or lack of resolution,” she said. “And sometimes what looks like an idyllic resolution after the loss of parents turns sour. Sometimes there are latent jealousies and unresolved conflicts."
