Last night's homework involved writing the numbers 3 and 4. "These are not relaxing numbers," DB says to me. "I need to write some 2's to relax."
And he did-- a whole page in his notebook! (Remember, this guy hates to put pencil to paper.)
Interesting echo of Daniel Tammet, an autistic savant who (among other talents) sees numbers visually, as landscapes.
By no means is DB a savant in this area -- his comment just reminded me of Tammet, whose book Born on a Blue Day had thoughtful insights I found helpful thinking about what goes on in DB's head.
