The little alarm bells during regular interaction, would have to go off in order for me to dig deeper. And, coming from a certain world of training, I listen to my instincts when those little hairs rise on the back of my neck. 
Very seldom have I ever felt that need. As to a reverse of that.....and more to the point without giving locale's and identities away, there's a woman in Northern Europe whom parted ways with me who, in another universe, was like a second skin with me. Some things became rocky and in the end, she departed angrily and I was never allowed to fully explain myself before she left. It's been what....a year? and she remains an aching in my soul. I miss her. I wish she would come back as, she knows I'm "around" among the websites we both frequented. And yet, I get it. A choice made.
I hope some time, she will surprise me and reappear. Until that time, I continue to turn my face in to the wind to hear the voices.
