This was in Seoul, South Korea (Where I'm from). It was all over the news there.
In Seoul, the elevators in the subways are for the handicaps only. This was one.
The lady, who obviously wasn't handicapped, used the elevator and didn't even wait for the man in wheelchair.
So the man got upset about the situation (I guess he was already suffering from depression) and started banging on the doors.
The doors finally caved in and he fell to his death.
Depressed or not, Handicapped or not, he's stupid for losing his temper like that.
