Re:Sounds like he has synesthesia (Score 1)

Synesthesia is not a forced association. It just happens naturally. And I do think this is synesthesia (I explained this above). The not being able to tell left from right is normal, as most of us are ambi-dextrous and quite a few cannot tell left from right. Affinity for language might also be explained with synesthesia - that's how I learned English perfectly within the span of a few years in high-school; even though he is autistic which usually hinders one's language abilities. Basically, I think he has extraordinary mathematical powers which are made more fun with the synesthesia.
