Hi Anu
You may be right, we've thought this before, that the threat of losing Pratigya might motivate him to get off his backside. So far, even when SS told him he has to buy the groceries he managed to get out of that, but when KN created this fuss, K sat there so casually without a care in the world, confident that his dad won't expect his ladla son to do any work.
He is only what his parents encouraged him to be, and he even thinks he's too old to get an education. P knew he wouldn't want to learn which is why she didn't even bother to try to suggest he goes to school/college or teach him herself. He feels he's above that sort of thing, which is what he's got to snap out of.
The only things i can think of are if P threatens to walk out on him, or if he realises his family have attempted to murder P a couple of times, and if they move out, he will have to work to support them. The trouble is they aired the 'Pratigya Niwas' promo about 6 7 months ago and still no progress in that area and that's what we have been waiting for.
