Examples

“Talk⟳ to enough grandparents and one thing becomes clear: Because she's closer to the mother of the children, the maternal grandmother generally has a slight advantage. Or, as Audrey Berson […] put⟳ it: "She's my daughter, so I have⟳ the edge." Even so, Berson's co-grandmother works in the same town as the grandkids, and she sometimes meets the bus after school. "It bothers me," Berson said. "I wish⟳ it were me."”

“A Canadian grandmother's essay about essentially crashing her daughter-in-law's birth […] Rhona Bennett writes of […] hopping a train⟳ to Montreal, and (in cahoots with her co-grandmother) bum-rushing the hospital […] The two bubbies called the hospital […] and naturally were rebuffed, so off they went, in search⟳ of information, affirmation, and a grandbaby.”
