This happens too often. The worst incident for me was when I was standing at a road crossing. A guy crossed the road towards me and stood behind me, he was stood too close for comfort. I felt a hand placed on my ass. My only reaction was to turn and tell him to fuck off, there was a girl I knew across the road who saw it all and never mentioned it. It made me feel so dirty and I still think about it now. Every time I walk past a construction site I feel incredibly uncomfortable because of past experiences. Hideous.
