Neighbors called her “Mama” with a smile, part-joke and part-affection; she had a way of listening that made people confide the small, strange things they didn’t tell anyone else.

She wrote little notes on scraps of paper, reminders to herself: water the plant, call an old friend, don’t be afraid to be small.
