"Of the Good in you I can speak, but not of the Evil. For what is Evil but Good-tortured by its own hunger and thirst? When Good is hungry, it seeks food, even in dark caves, and when it thirsts, it drinks even of dead waters." ~ Kahlil Gibran
Anyone. Everyone you cross paths with has a purpose and has something to offer whether you realize it or not. It could be anything from a hug to a hard lesson.
