Love demands expression. It will not stay still, stay silent, be good, be modest, be seen and not heard, no. It will break out in tongues of praise, the high note that smashes the glass and spills the liquid.
Perhaps all romance is like that; not a contract between equal parties but an explosion of dreams and desires that can find no outlet in everyday life. Only a drama will do and while the fireworks last the sky is a different colour.
