Why and how has mammy changed?

Laila's mother feels lost since the death of her sons. She looses much of her motivation. She collects mementos of Ahmad and Noor's fight against the Soviets, including news clippings about Soviet attacks on villagers and children. Fariba stays in bed all day and has a lukewarm reaction when Laila tells her that the boys squirted her with urine. Laila sees the Benz leave from Mariam and Rasheed's house. Laila's mother promises that she will pick Laila up from school the next day.
