@arathim - Nandu has done many things which are as bizarre and as silly. Her falling down awkwardly is an accident- it happens during beauty pageants live on tv , but contestants are applauded for taking it in their stride.
Nandini Moorthy is loved because she is human and real , not a mannequin , which means she is prone to accidents like falling down . It is not something that is new, like I mentioned previously happened to her when she was hastily rushing for her job , she fell down - big deal. She ran across an airport , got everyone kicked out of the plane because she wanted to transport her fireflies- silly, childish but her.
Dignity is an individual thing, nobody can make it or shape it except of the that particular individual , also he/she will have their own definition for it. What you are aiming at is impression- you feel bad and that is your reaction or impression of that situation. Whereas for some of us , it's an accident aimed at showing Nandini's rush and impulsiveness .
The reason why we are at it because the word Dignity or character assassination are far fetched and probably silly, perhaps a bit dimwit as you might call it because all it was was an accident, caused by friction or something, nothing more. If we are to remove all sorts of taboos on female behaviour or etiquette this should be a good start.
