“They’re getting engaged in December,” my friend told me one afternoon. She was talking about our mutual friend and her boyfriend, who were both in their early 30s and had been together for around three years.

“Makes sense,” I said, but I was curious how she knew this information. Did the boyfriend confide in her about his plans to propose? Had my friend asked him? Or did she just have some kind of psychic intuition about the timing of it? None of these turned out to be the case. It was the bride-to-be, my friend explained, who was helping plan her own proposal.
