Leela is in her sixties and works seven nights a week.

She has been employed to look after Preeti, a woman in her eighties with dementia. Leela keeps her safe through the night. Her duties involve preparing her charge for bed, then hours of fitful half-sleep, when she springs from her mattress on the floor if Preeti wakes (she often does), the morning lavatory run, including the hand-washing of any soiled clothing and sheets, the daily bath. At nine in the morning, her shift ends.
