So, I'm riding the subway on the way to Itaewon. Beside me is a boy (about 12 years old) and his father. The train stops at a station, and when the boy turns his head away from his father, the father very quietly and quickly gets up and slips out the open door. A few seconds later, the boy turns back to see his father gone. He looks around, confused, muttering something that probably translates as "Wha... I... wha?" He then catches sight of his father looking at him from the platform laughing his head off! Soon, a number of passengers (myself included) are grinning and smirking, doing all that we can to not burst out in peals of laughter. As the train pulls out of the station, the father signals his son to catch the return train at the next station. Needless to say, it was extremely hilarious.
I'm sure the child-abandonment issues and psychologist bills will be well worth the lols.
