In the show whenever she is having dialogue with her husband Anshuman sometimes she used the word " Aaap " to address Anshu however I notice that sometimes she quickly switch from "Aaap" to "Tum " which I found very puzzling .
Hindi is not my native language, that's why I have no idea , is it common in Hindi language at the same time calling husband Aaap and Tum simultaneously ? or its the fault of script writer ?
Any explanation ?
