I thought I gave it? I walked her late at night in a local park. The park was empty bar me and her. A man, talking absolute gibberish approached me at the park (I had my back to him initially) and as I listened I realised he wasn't "all there". I tried pretending I didn't hear him but he just kept talking at me. My dogs just sniffing around the park at this point. I realise he's not going and still trying to get a response from me. So, I finally turn around to say something like "please leave me alone" but before I could say a word, my dog, who's never barked or been menacing to anyone before, seemed to notice my fear and so she starts barking at him and jumping around him (about 5 feet in front of him, placing herself between me and him). He gets the message and leaves. Is that the back story you were after? If not, please explain. I could talk about my dog all day.
