Everyone has their own story to tell. Sometimed, the world doesn’t need to know everything that happens in our lives. A person's 'character' is shaped by the environment they endure partly inherited from their parents, and fully formed by the actions of those who broke their heart. Do not assume your feelings are always right, for one day, you will feel the exact same pain, even if fate isn't ready for your actions when 'that day comes.'
Because, in the end, not everyone you count on will actually show up for you.
