W: Sorry, I’m late. The train was delayed. I got stuck on the platform for about 20 minutes.
M: Yeah, it happens from time to time. How are you finding the commuting anyway?
W: Well, it’s a shock to the system to be honest. Last night I was coming home from the office, and I got caught in the mad rash in Shibuya. It was unbelievable, everyone jammed in like sardines.
M: Yeah, and then just when you think there’s no way anyone else could fit on, five more people barge through!
W: I’ve got a hand IT to the train companies though. Whoever devised the schedules is a genius. It’s amazing how different trains arrive at the same time for people to change.
M: I know. Back home, 20 minutes late for a train is pretty standard!
W: So what do you do to take your mind off things on the train? I tried to read a book, but I couldn’t turn the page—not enough space!
M: I usually listen to music, it helps block out everything. But if I’m really tired, I tend to just nod off for a few minutes.
W: Isn’t that a bit risky? You don’t wanna miss your stop.
M: You watch the businessmen do it. They have it done to an art form. They’ll wake up just before their stop.
W: I’m afraid if I close my eyes, I won’t be waking up so quickly!
