If the man is REALLY trying to molest, just shout in an angry manner, "Pervert!" or "Hamsap!" and move to the other end of the bus or train AWAY from the person. He'll be scared cause other people will be staring at him and he'll leave instantly on the next stop. If it's on the bus, I can safely assume that maybe the bus conductor will even kick him out. I've heard of cases like these before.

They would rather have one passenger leave the bus than the rest of the female passengers stepping out at the same time.

Have to be tough lor... us girls sometimes have to make a scene to protect ourselves rather than feeling scared that people think you're crazy or b*tchy.

I'm just thankful I have not experienced these things and hope never to go through it!
