Last week, I was having a conversation with a friend of mine, I asked her the same question, which I ask myself quite often, though it is not applicable to me.

Why are people SO bitter about their past ? Is it because they still care, is it because there is a part which they can not let go ?

Why don't they remember the good side of things, sure they've had their fun, so why not ? Is hatred so strong that it engulfs every thing in sight, the good times, the fun, the laughter, the joy, the promises made to one another.
