Writing is her everything; she expresses through paper what she can't say with words.

My relative is worried about her because even if they're best friends, there are lots of things that she's hiding; it's like if they only stand each other because they get along well.

She may have inner issues; we don't know, and that's why, as a student of psychology, watching her every move in a place she frequents is my duty to try to understand what makes her so mysterious.
