In this brief flashback, the details of Mr. Chawla’s past reveal more interesting facets of his character. As much as he makes a show of berating his family for their abnormality, he actually feels a sense of purpose and pride in contrast to them. Where his wife and children are strange and socially unacceptable in his view, Mr. Chawla gets to act as the cornerstone of order and rationality he’s always wanted to be. This highlights how his sense of self is firmly rooted in the idea of traditions, customs, and social norms. His family might frustrate him, but they also give meaning to his life.
