How is it that something can be good and bad for you at the same time? Maybe you can't understand it until you experience it. It is like being colorblind your whole life, and then waking up one day to realize that you can see colors.
It is true that some things in life are black and white, but then again, some things aren't. There is a world full of colors out there; you just have to open up your eyes wide enough to see them.
Maybe a person you thought you knew turns out differently than you expected. Maybe they have done something and you just don't know what to make of it.
However, in this world full of colors, shouldn't we all be given a second chance? Wouldn't you want to be? If nothing else, if we cannot do it for the sake of the other person, can't we at least do it for ourselves?
Sometimes forgiveness is the only thing we have left.
