Think twice about leering at women on public transport.

It’s hard to be a woman and the number of perverts on public transport doesn’t make it any easier.

Liaoning Satellite Television reports that a woman, Miss Wu, was forbidden from wearing spiky “anti-pervert shoes” onto a plane. She explained that beautiful women had to protect themselves from the large number of perverts who are out there.

A character in the new film “Lost in Thailand,” which has already become the most bankable Chinese film of all time, brings a bag with similar spikes onto a plane. But I suppose this is one of these gray areas when it comes to what we can and cannot carry on board.
