well ...................i don't think pratigya slapped angad by thinking that krishna or sakthi won't be able to do anything....................it was just a natural and reflex reaction from her....i mean would anybody in this world just stand there silently and let him talk abt ur sister the way he talked.....any normal person would have totally gone mad and tried to cause him as much pain in that insant with whatever resourses r available like ur hand or leg or any other thing which u could lay hands on.....ur brain just can't think in apractical way in such situations........i think pratigya wasn't even thinking anything but to cause him max insult and pain and punishment for harassing her family and bad mouthing abt her sister...........and she is justified .....fully............i had read a story abt a nexlate women many years ago......she was captured by police and put in jail without a case being filed.......and the officers and constables tried to rape her.....u knw what she did?........when she knew she can't overpower them she just tore open her blouse and challenged them to touch her as if she was being possessed by a ghost or something........and that outburst put all those namards to thier places.......they didn't dare touch her.....so did she do such an act to make it easier for them or welcoming them to have her? no......... it was the last attempt to save her izzat of a self respecting women who could not even end her life herself as she didn't have any means to do so.........did such an act make her stupid.......? no instead it made her more braver than the whole mankind in the universe.........so raecting to circumstances instantly wouldn't make u stupid or in any way immature......it makes u more human.............just my thought.........
