Reviewing his notes I discovered he plays tennis. Quite well. He already has a couple of trophies.
Apparently there's good genes for tennis playing in his family. Not to the extent of making the professional circuit, but immediate family members have made it to regional representative level.
I really want to ask his Mum if he's named after Rafael Nadal. I'm hoping it might come up casually in conversation if I ask her what she thinks his eye hand co-ordination is like.
