woh uski jhijak h kyunki children will learn the definition of a relationship by witnessing their parents' behavior in it...bade hoke toh they will understand why the parents split or whtever pr in their case, dad came home after work & nvr took much interest as he assumed they are bound to get married ...garima may have respected her father's hardwork but she never supported his mentality hence why she feels that correct wording is required to speak the point whereas susheela doesnt like to beat around the bush & likes to get to the main pont...
Both have learned about relationships from their parents, that is why it is taking them time to trust real love now.
