One order of the usual coming right up! 1 course of "Why does XXX not work for you?" a la francaise, where XXX is, in your case, the Euclidean distance. Specifically, any metric worth its salt (in a normed space) satisfies dist(a,b) = dist(a+c,b+c) so why are negative values a problem?...
2 sides: a "Minimal Working Example" with a light buttery sauce and a fried "what package/code are you using" and, for desert, a Winsemian special of: "read the posting guide!"
