Picture memory.

This week it has become more clear to me that Christopher has a great ability to recall anything that he has seen before.  One example, we drove past a place from an entirely different direction and he knew not only that it was his friend Sarah's house but also was upset when we didn't stop by.  Off to the grocery store we had to go. That turned out fun too because while there we saw our friend Hannah out of her normal context and he talked and talked to her even after she was down the next isle.  "what r oo doin?  why here? wit ome back! whur u go??"
