Ok, I agree I am not fan of Shreshthababu's negative tone. But hey, let's get over the tone! This guy got some point that is worth discussing. 

One of the very big setbacks in Nepalese societies is its hierarchical systems. There are almost unpenetrateable strata where people set up. Do some people jump from one to another, yes. There are many symbols people like to maintain to signify/glorify their level. In other words, people project many ways to feel good about themselves. The devise languages, attires, traits so that there is some constant reminder for them. 

What Sexy-in-Sari is saying: I couldn't agree with you more about carrying forward 'proper etiquettes and manners', but I invite you to present a fact based on whether this 'etiquette' is shown indiscriminately to everyone or to only certain people? Be honest, dear. In Nepal, would you address your 'mula and carrot produce' with the aaishyo? To a janitor brooming near Lainchaur? To a vegetable vendor 'madhesi'? Are they in that 'aaishyo' category? One needs not wonder.

Do I have problem when people address each other with that? Heck, no. But lets not sugarcoat it with 'manners'. Sometimes cigar is just a cigar. Nepal is a super hierarchical society, which seems to be getting worse.
