Sasur Ji would be a fool to allow his daughter to leave her home and come sit in his because she found emails from years ago. Laad uthana alag baat hai but apne haaton se apni aulad ka ghar bigarna alag. No parent should be indulging in such behavior.
If it was my daughter, I’d smack her and send her home. If it was my son…the one I have right now…I’d do the same.
