I recently talked with an identical twin in her late twenties who shared an interesting conversation she had with two female cousins a few weeks prior. The three of them were talking about weddings, and my patient, Mary, told them her sister would be her maid of honor along with her best friend.

This comes as a shock to both siblings, who previously believed that their partnership was inviolable. The story of a pair of identical twin men, who are now […]
