The Tamil language most times has some rather succinct concepts to describe situations.
For this situation explained above regarding Mamta and her ideas, there is one apt word in the Tamil language to reply to her::
PODI
P.S. :: Apologies to non Tamilians on this board, approximately podi translates to go-to-hell-you-female. Apologies to Tamilians on this board who understand the aptness of podi in this context and are apalled by my poor translation of the same!!! lol
