While getting out of the mrt train at my station, I found a couple feuding at the top of the station's escalator. The other commuters had to step around them in order to go down the escalator and the couple was so caught up they didn't bother to move away at all. The girl was trembling visibly with anger and she said loudly in Mandarin to the guy that he made her sick. Everyone pretended not to hear and scuttled away as fast as possible. The couple must have been really overwrought to have a showdown right there and then, so overcome that they forgot where they were. I hope they can sleep tonight.
