In Ch. 2 Dr. Aziz and his friends are having a "very sad talk"…" they were discussing as to whether or not it is possible to be friends with an Englishman:' The discussion that follows characterizes the different personalities that figure in the novel in terms of this possibility of friendship. According to his friend Hamidullah, all Englishmen "become exactly the same, not worse, not better… All are exactly alike." Hamidullah's experience tells him that friendship is not possible, because Indians will always be viewed as inferior to the English.
In Ch. 3 Adela Quested, recently arrived in India with her presumably future mother-in-law, exclaims that she wants "to see the real India" (italics not mine). After some cultural misunderstanding between Adela, Dr. Aziz finds himself in the position to host an excursion to the Marabar Caves for his newly found friends, Mrs. Moore and Miss Quested.
Think about what "friendship" implies and make a prediction as to how Forster begins to answer or at least address this possibility in the first half of the novel.
