Can you give me some examples of how Tom Sawyer comes of age in The Adventures of Tom Sawyer?

I think there are many examples of Tom coming of age. When
he gets the boys to whitewash the fence, using reverse psychology, because he doesn't
want to do it. How many present day kids could do that? He falls in love with Becky and
imagines and stages his own death, quite a thinker. The later engagement to Becky and
Tom's admission of a prior relationship shows
honesty.

After the murder of Dr. Robinson, the boys swear
to remain silent. The later rafting away exemplifies guts and fortitude. When he
exonerates Muff at the trial is another excellent example of his honesty and wanting to
do the right thing. Later when he hides in the caves with Becky, even though some would
say this depicts his childish nature by hiding, I think it is another example of him
having courage and certainly coming of age.
