One of my favorite household chores in India is hanging laundry on the roof. A soothing time of contemplation. Washing machines are front loaders and very small, so the Indian housewife washes frequently.
The alternative for most Indian women is washing clothing in the river and beating them on a rock. Then they hang the items wherever they can--on fences or over bridge railings.
In my novel, Chosen Ones, Constance hosts a tea party for Maggie and Yvonne on her roof top. Many Indians deck their roofs with gardens, a lovely sight to behold!
