How does a lack of communication lead to a lack of emotional connection in the Interpreter of Maladies? Can this be used as a theme?

The lack of communication between Mr. Kapasi and the Das family leads to a lack of emotional connection by making it hard for the parties to comprehend the mannerisms and behaviors of each other. First, Mr Kapasi is shocked by the way the Das family treats each other; the father and mother (Raj and Mina) act like older siblings instead of parents to their children (Bobby, Ronny, and Tina). According to Kapasi, Mina seems to hate doing things for her kids since she complains about taking Tina to the loo. Kapasi makes the presumption that the entire Das family is made up of children. Had he bothered to ask them why they behave like that, he would have understood that both Raj and Mina love their children, and constant arguments are their way of showing love. Kapasi's misinterpretation is evident in the final incident, when Bobby gets attacked by monkeys. He takes his time to observe what the parents will do and is almost surprised when they ask him to protect their child. Alternatively, if Mrs. Mina was actually interested in what Kapasi does, she wouldn't have asked him to interpret her emotions after revealing the secret to him. It shows that she was only flattering him so that he could make her feel better.
Yes, the lack of communication leading to a lack of emotional connection can be used as a theme, because it has an effect on the entire plot of this story.
