George Parnham, an 85-year-old lawyer, makes weekly phone calls to a list of people, including family members and a woman named Andrea Yates. These calls have become shorter over time. Parnham's routine involves checking in with those on his list, asking about their well-being and the weather, before crossing off their names.

Andrea Yates has been associated with the issue of postpartum psychosis for 25 years. She is a former suburban stay-at-home mom who was plagued by delusions about her children.

Further details about George Parnham and the Andrea Yates case are available from the source, including photographs and additional background information.
