Sunit, 29, a software engineer in Bangalore, has a typical headache. “My mother has started ‘casually’ mentioning girls from her WhatsApp group. Yesterday, she left a rishta (proposal) photo on my pillow. It was inside a book. She thinks she is subtle. But the whole house knows. My father gave me a ‘thumbs up’ behind her back. My sister is laughing. I am going to pretend to work late tonight. But I will look at the photo in the cab. Maybe she is nice. You don’t date in India. You investigate.”
