Edith has a lifelong antagonism with her sister Mary. Does her Enneagram number provide a clue why?
Ah, she’s very much an Envy person. Mary is mean to her, but Edith wants more than niceness. She wants Mary’s position of respect in the family. Mary is unflappable, while Edith is gently injured by every unkindness. Command comes easy to Mary (because she’s the eldest, and an Eight); Edith struggles to find her place.
Of course she’s a Two. That’s why she and Mary are at loggerheads. They’re each other’s strength and weakness number. It’s also why Edith can never get ahead. A Two is supportive and caring — an easy person to take for granted, especially when an Eight sucks all the oxygen from the room.
And Edith has a moment when she does something cruel. She informs the Turkish embassy, solely for revenge, of her own sister’s indiscretion with their diplomat. When a Two slides into weakness, that Eight quality dominates in a poisonous way. Edith is very unlikable in that sequence, but now we see she’s true to her character. We just prefer her as the nice, dependable Two person.
