Explain the causes of the gang's deliquency, including their reaction to the name Trevor and their reaction to Old Misery's gift of chocolates.

The Wormsley Street Gang, made up of young boys who grew up in post-Blitz London, have lived in a world full of destruction. They are so entrenched in the hardship and difficulties of post-WWII life that they are at a loss when confronted with beauty or kindness. When Old Misery offers them chocolates, they cannot understand a kind gesture, but rather suggest that the chocolates are dirty, stolen, or a bribe. As far as T's real name, he drops it because "Trevor" is an upper-class name, and the boys have working-class disdain for anything of that sort. These attitudes are the foundation of their decision to destroy a beautiful and historically-important home built by Christopher Wren.
