How did they get to this situation?
The portrayal of a 12 year old and a twenty-something year old on the fringe of society rings true ...assuming the world started yesterday.
But in real life, before he can be 12 he had to be 11, and before that 10, and so on. "The past" seems to me to not ring so true. Specifically:
- if he never went to school, how did he learn to read? (he had no trouble at all with the oven setup instructions)
- how did he support them over summers?
- in my experience, a kid growing up like that would by now have severe behavioral problems, be a complete sociopathic monster; but he's not, why?
