For me it reminds me of a boy I knew growing up who later got diagnosed with Asperger's syndrome, who was absolutely enamored with trains. He was very smart, if awkward at times - I always liked hanging out with him when he was in his element. But even early on I think he knew something was off, because he constantly asked questions along this line when we did things like play Halo co-op together. "Am I being helpful?" "Am I useful?" Once I got so annoyed by these questions I just said No and he didn't talk to me again after that. There is something deeply, deeply sad to me about thinking through what kind of family life he might have had that he even felt the need to ask that question. I didn't grow up in a great environment either, but I never had any doubt that I was doing good things that would be a point of pride to most parents.
