Okay if she does not want to disclose where she was going and other matters but she could have explained it politely that she could not disclose due to some constraints. Instead she was abrupt and it seems that she deliberately wanted to mislead the family. So that she will become mahaan in their eyes when the truth will be disclosed and make them feel guilty and ashamed.
Suppose if she had to help one of her maika in this manner, would she have been forgiven and applauded so wholeheartedly? Or would she have done the same thing to her maika with such abandon?
