The IT Couple

My life was normal. I was a good sister, daughter, and stayed to myself.
But if you were to tell me that I would have been hurt by the people I love the most, loved by the person I hate the most, and tormented by the memories around me... I would have laughed in your face. But change is one hell of a bitch.
And it takes one person to make that change, that very drastic change, worth while.
The question is... who is that person?
You tell me.
