perfection is by any way of looking at it, something very personal to whoever is viewing it, and their opinion of it is what makes it perfect.
To me, perfection is something I couldn’t be happier with, no matter how it was changed to try to make it better.  That’s not without saying that it can be changed and still be perfect to me, some things can be perfect through the variety and shifting nature of them. A perfect song, yes please. But only that song to listen to for the rest of my life, with no changes to it? no thanks.
