A friend of mine was walking home and noticed she was being followed. She decided that she’d try to get home safely as quickly as possible, so she hailed a taxi that happened to be going past and he drove her home. She told the driver what had happened, at which point, he put his hand on her knee and left it there for a while. I know it’s hard to tell what’s happening, it’s hard to tell harassment from someone a little bit too touchy-feely with you. But that’s part of the problem. She felt awful after that. He made her feel even more unsafe, and that’s what makes it harassment.
