To Samuel and Ashraf the grammar of adults is only in the imperative form. Adults control punishment and affection. When adults failed them, Samuel and Ashraf chose the status of adults for themselves, on the street. They believe they are free. It's a brittle freedom, though.
Survival still depends on gaining the sympathy of adults.
I have seen Ashraf walk up smoothly to a passing stranger, take his hand, let loose a sob story, and pocket three dollars, enough for a burger and two hours of video games. Survival means he must auction his biography. Going, going, gone. I got up to pay the bill. It was night.
