Step-by-step explanation:

"One day, the sweater disappeared. Gone. I can't articulate the contradictions I felt. Relief-some thing had taken it at last, and loss all over again. That swath of ultramarine had hung like a spirit friendship with a woman I never knew, but I did know because of her skill and her daughter's gift. It also stood for my lost friends. Their spirits, that blue. I studied the ground under the clothesline, scuffed through the garden, searching for the remnants. Nothing."
