Even if it wasn’t your fault, it is your problem, and you get to choose what you do in the aftermath. You have every right to rage and rant and hate every iota of someone’s being, but you also have the right to choose to be at peace. To thank them is to forgive them, and to forgive them is to choose to realize that the other side of resentment is wisdom. To find wisdom in pain is to realize that the people who become “supernovas” are the ones who acknowledge their pain and then channel it into something better, not people who just acknowledge it and then leave it to stagnate and remain.
