“A cynical type might suggest that it was all too perfect. But a cynical type would be wrong. Matt and Maeve weren’t just acting the part of people who are Very Much In Love. It was the real thing because their heart vibrations were in perfect harmony.
Not everyone knows this but each human heart gives off an electric current that extends outwards from the body to a distance of ten feet. People wonder why they take instant likes and dislikes to people. They assume it’s to do with associations: if they meet a short, mono-browed woman, they remember the time that another short, mono-browed woman had helped them get their hairdryer unstuck from a hedge and cannot help but feel warmly to this new, entirely unconnected, short, mono-browed woman. Or the first man who short-changed them was called Carl and from that day forth all Carls were regarded as suspect. But instant likes or dislikes are also the result of the harmony (or disharmony) of heart currents and Matt’s and Maeve’s hearts Beat as One.” — a supernatural entity (kind still to be determined), The Brightest Star in the Sky by Marian Keyes
