There's no particular reason that they need to put it back together. I mean, it would be great if they could be friends--the more people who are friends, the better. But I think people are a little too overly focused on resolving things at all costs, even when they've had multiple blow-ups. Sometimes, you have to be willing to recognize that a certain relationship isn't going to be productive and move on, without acrimony and drama.
I'm not saying that that's the case with KingSpeed and HCP, but people in general shouldn't be obsessed with making relationships work, unless they're deeply important ones. There are other people on this forum that keep trying to "talk things out" and just results in more strife and arguments.
