A fan mechanic of my friends house (after repairing the fan of her room) came to her house 3 days after he left.He said "would you like to have sex with me?Actually it is just for fun.You are very sexy and cool just like I wanted.Please donot refuse."But my friend refused and he is disturbing her everyday now.Even he is telling her that if she refuses,he will kidnap her and will perform it.She told to her parents and they told not to bother 'cause nothing will happen.But she is worried.What to do??
