That reminded me of something. When I was younger I had an issue with an older neighbour that had an inadequate behaviour towards me. He acted normal when he saw my parents, though, which confused me at first. But he was disrespectful and slippery.

As his behaviour never crossed the line and never grew into something more dangerous, my parents opted for the "good neighbourhood policy" because he had a daughter of my age. It still pisses me that he got away with that. I felt humiliated when I saw my parents politely greeting him and that's something I'll never do with my kids. I didn't want to see anybody's life ruined, but I don't admit people making me feel uncomfortable either because I'm a woman, because I'm younger or because I'm in a lower hierachical position at work. Sometimes being permissive with such behaviours is what make them grow worse.
