A person so enthralled with polyamory they forget about monogamy and monogamy-oriented thinking altogether.
John called me and said "Great news, we are pregnant!" and I am so polycentric my first words were, "Congratulations! Who is the mother?" Then I remembered he is in a monogamous relationship, so I guess his wife had better be the mother!
