At dinner Ethan launched into his routine of "Did you know..." and today it was the little known fact that "...hedgehogs can have up to five million spines?"
No I hadn't known that.
Earlier in the day I'd received a text in which someone told me they'd sorted out Tom's birthday party and could I hold the date. I have no idea who texted me and I had no idea which Tom was having the party. I consulted the children to see f they could shed light on the situation.
Ethan named the two Tommy's in his class with their exact birthdays. How did he remember that?
I told Ethan he must have a huge memory, a huge hippocampus and there then followed a discussion about the difference between a hippopotamus, a hippocampus and a hittopotamus (what Ethan used to call a hippopotamus and, if I'm honest, still does).
We talked about London cabbies and their extraordinary memories because they need to learn the Knowledge and experiments have shown this results in enlarged hippocampi (plural of hippocampus?)
Dave piped up about the Dichotomous which is a large, two-headed, plant-eating mammal that lives in water, and to round things off I told him about the Monotonous which is a large, boring, plant-eating mammal that lives in water.
