After you lose something, you come up with a bunch of reasons as to why it was okay to lose it in the first place. Ex. It was old, the color was faded, the paint was chipped, and so on, amirite?

and in your case "it only contained a part of my soul in it. I have 6 more of those anyway"

then you find it and that's all you can see

Like how lord voldie lost his integrity in the 7th book

It depends on what it is.
