My hundreds of boys and girls never cease to amaze me. I was threatening them with dire consequences if they didn't study hard enough, saying I'd seek their parents' permission to keep them in my house and entirely under my supervision for a month or two, and send them back vastly improved. And I said I'd look after everything, from diet to potty habits to exercise to following strict work routines. When they expressed curiosity about the diet, I mentioned that among other things, they would have to eat a lot of fresh green vegetables. To which someone muttered 'amra goru naa ki' (are we cows or what)?
What does that say about their parents' ideas regarding matters of nutrition? Remember, too, that all these parents are highly educated...
