Hello,
David is thinking about his quest for manhood, which he connects with
owning a gun. Because he is “almost a man,” he believes that he should
own the symbol of manhood: a gun. Borrowing a mail-order catalog from a
local store owner so that he can look at the pictures of revolvers,

important, the strategy that he must use to persuade his mother that he
should be able to buy a gun. A real man doesn't need a gun.
