Why does Mr Pirzada begin coming to lilias house?

Mr. Pirzada begins visiting Lilia's house as a result of his need for companionship and a sense of connection while he is in America, away from his home in Pakistan during a period of political upheaval. He forms a bond with Lilia and her family, sharing cultural experiences and his concerns about the situation in his homeland. His visits also serve as a way for Lilia to learn about her heritage and the realities of the world beyond her immediate surroundings.
