Imitation is ABSOLUTELY the sincerest form of flattery, so try not to be too offended when it happens to you as it almost certainly will. Copycats are jealous of a peculiar capability that you possess and in light of the fact they do not possess this capability and never will, they next do the easiest thing and pilfer from you. But don’t fret the issue; all is good. The guilty party may think they are outsmarting you, but the plain truth is they are stealing the golden egg and not the goose that created it. These varlets can never steal the creative spark that generated an inspired product; that entity belongs only to you and no amount of mendacity will ever alter this fact.
