I can definitely resonate with this line: "Once people start coupling up, the challenges only increase. Making friends with other couples “is like matchmaking for two,” said Kara Baskin, a journalist who works in Boston." From experience, finding new couple friends appears to be impossible. The difficulty is even quantifiable. For example, to make a friend person A must like person B, and vice versa, or expressed as a permutation: P(2,2)=2 units of difficulty. But to make a couple friend the difficulty increases to P(4,2)=12...a 6x increase :( Has anyone had success finding couple friends?
