Right and Left
Here is the determination I have known since day-one. In this instance, applied to the jungle-gym but it could easily by Kumon (maths), the classroom, football &c. It is also applied to her brother who constantly rags her these days. I tell Madeleine that Eitan has her button, and after explaining what this means, I advise her the best solution is to ignore him. This is, like, totally impossible so instead they trade blows in the back of the car until somebody (me) screams bloody-hell. Yes, we are at that point in the holiday familiar to all vacationing families: we are about to kill each other.
I learn a cool thing today which I have always puzzled: why is Paris's Left Bank called, well, the Left Bank? It doesn't seem this way on a map, I mean really. The "right" and "left" are determined by the directional flow of the river. So the Left Bank is the left side of the Seine going with the flow.
