I was rushing to town for an appointment this afternoon (Wed) at 5.20pm, and whilst I walked into Hougang MRT station, 50m away from the gantries, I heard very loud shouts (not of a child but a male teenager). As I walked down the escalator to the platform, I saw this upper secondary student (Judging by his long pants; I shall refrain from revealing his school) standing beside the escalator, pulling his own hairs with both hands and shouting to himself at the top of his voice, very very loudly! People in the station was stunned by him, and I saw several MRT station operators going towards him, and at that point I boarded the train, and didn't see what happen after that.
But it makes me think, these days what makes students/teenagers so stressed, that they can snapped just like that? It's so sad.
