I was chased down the road last year by a man who demanded that I give him "just a little kiss". He had stopped me while I was walking (at 3 in the afternoon, wearing headphones), apparently to ask for directions. Although his destination was in the opposite direction, he followed me down the road for what felt like forever, shouting abuse after me when I refused to let him hug me, or kiss me. He clearly thought my body did not belong to me, but to him. Not one person stopped to help or to offer support, although there were plenty around. If you see someone in distress in the street, lend a helping hand - go to the victim, not the harasser, and ask them if they need anything, if you can be of assistance. Everyone has to play a part in preventing harassment, and in showing harassers that their behaviour is not to be tolerated.
