BAGHDAD, Nov. 19 — Five months ago, Suhaila al-Aasan lived in an oxygen tank factory with her husband and two sons, convinced that they would never go back to their apartment in Dora, a middle-class neighborhood in southern Baghdad.

Today she is home again, cooking by a sunlit window, sleeping beneath her favorite wedding picture. And yet, she and her family are remarkably alone. The half-dozen other apartments in her building echo with emptiness and, on most days, Iraqi soldiers are the only neighbors she sees.

“I feel happy,” she said, standing in her bedroom, between a flowered bedspread and a bullet hole in the wall. “But my happiness is not complete. We need more people to come back. We need more people to feel safe.”

Mrs. Aasan, 45, a Shiite librarian with an easy laugh, is living at the far end of Baghdad’s tentative recovery. She is one of many Iraqis who in recent weeks have begun to test where they can go and what they can do when fear no longer controls their every move.
