My sister flunked her exams 10 years back and from that time she kept on changing she first failed during her 10 th standard exam. and then again after 2 years..and again after 1 year.. and then she started making fake stories..she will see some new spaper and tell these guys were following her..she thinks it is real..my mom too supports her now..they think that she won some art certificate which is very important ..and they think and talk foolish and stupid... they are making their own world together they think that the world is after them to get the certificate..like that everything else is normal..they dont want to meet any doctor for the fear that they give medicines which create side effect... they dont behave violent as long as we accept what they say..i mean my dad and me..dont know how to get it cured now..? very hard situation.. both of them are making their own fakeworld.. they think they are genuinley right...
