The first time my sweetheart crossed my path I was in no mood or frame of mind for anything beyond my own sad story. When we crossed paths the second time, she was well prepared with my trigger words and actions. And I was broadcasting on all channels my desire for a partner to step up and be enveloped in my madness.
