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 gang's delinquency is caused in part from growing up in post-World War II London, which was destroyed in the Blitz, and from their anger at the class system. They react to the name Trevor with derision because it is a rather posh or upper-class kind of name. Trevor, or T. as he comes to be known, is from a family that is higher up in the class structure than the families of the rest of the gang. T.'s father is a former architect, now a clerk, and his mother considers herself above the other people in their working-class neighborhood.
The gang reacts to Old Misery's gift of chocolates with anger and suspicion. They think he is trying to bribe them or that he picked the chocolates up off the street. Their suspicion arises partly because Old Misery is from a higher class, and the gang doesn't trust people like him.
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.
the Trevor's name is a high class name, and in that poor society that they lived it was funny to use that upper-class name. their reaction to old misery's gift was because of the hard and cruel situation they lived in it, and kindness was something unfamiliar to them.
