From a New York Times story by Catherine Pearson headlined “The Lifelong Gift of Sibling Friendship”:

Sisters Audrey Findlay, 75, and Barbara Rowe, 63, start every weekday with an 8 a.m. phone call. An hour or so later, they head to work together at Findlay Rowe, the gift shop they opened 12 years ago.

At 5 or 6 p.m., the sisters leave work and head to their homes — four houses apart. And after dinner, they reconvene for an hourlong stroll, slipping easily into what their adult children (they have nine between them) affectionately call their “twin talk.”
