Paragraph 5
Biddy, too, 
(1)
signifies honesty and warmth in the
novel. 
(2)
Because he has fallen in love with Estella,
Pip grows increasingly unhappy with his life at the
forge and dreams of being a gentleman so that he
can win Estella. He discusses his feelings with Biddy
and clumsily states that he wishes he could fall in
love with her rather than the proud Estella. ‘But you
never will, you see’, 
(3)
Biddy states, because she has
the insight to understand that Pip has been smitten
and that the life of the forge will never satisfy Pip
now that Estella has told him how coarse and
common he is. Biddy, by asking Pip whether he
really thinks that becoming a gentleman will make
him any happier, reveals her understanding of
human nature.
