Sarah is a lonely teenager who is full of hidden, bitter passion. She shares her feelings only with the Mentor whom she met on the Internet. The Mentor supports the desperate girl every time she turns to him for help, although they never met in person. Sarah can communicate with him using live website chat. She shares her thoughts with him about being bullied and ostracized at school, her parents’ divorce, her mum’s new boyfriend appearing in their home; about everything that makes Sarah disappointed and upset. The mysterious stranger suggests that as time goes on, everything might get worse and worse, so Sarah has to strengthen herself in order not to get hurt any more. This is the reason why the girl trusts her Mentor blindly and accomplishes all the tasks given by him.

BTW, very nicely formatted first [REQ]uest. Unusual and appreciated.
