Euan was Scottish and Mimi was French. When they got together their friends called it a clear case of bilateral nominative determinism.
At first they always agreed in first person – Euan said ‘aye’ and Mimi said ‘oui’.
But then, then.
“It’s all about Euan, isn’t it?”
“Oh, very funny. Mimi Mimi Mimi, that’s all I hear.”
They were a contrapuntal couple until the centripetal became centrifugal. Euan said ‘aye’ and really meant it: Mimi said ‘oui’ but it never was again.
