Another update:

On Friday when I picked DD up from school she said one of the boys had a basketball game the next day and asked if we could go watch. Of course we did, even though it was almost an hour away from our home. She sat quietly, watching it all intently as I chatted with his parents. Yesterday another of the boys made a point of telling me he was going to basketball practice after school. (Who knew basketball was so popular?) Anyway I told him that if he tells DD when he has a game we would come cheer him on too. He fist pumped and jumped in the air - so, so happy.

When I later told DD how nice I thought it was that she wanted to see the boys play she said very matter of factly "Really Mom I just want to understand what the heck they're talking about all the time." So I think she's figuring out the anthropological approach all on her own. She and I both still wish she had some female classmates but it all seems to be working out..
