W: How are things going, Roald?
M: Not bad, Jane. I’m involved in several projects and it’s a long working day. But I’m used to that so it doesn’t bother me too much.
W: I heard you have moved to a new house in the suburb. How do you like commuting to London every day? Don’t you find it strained?
M: It was terrible at first, especially getting up before dawn to catch that 6:30 train. But it’s bearable now that I’m used to it.
W: Don’t you think it’s an awful waste of time? I couldn’t bear to spend three hours sitting in a train every day.
M: I used to feel the same as you. But now I quite enjoy it.
W: How do you pass the time? Do you bring some work with you to do on the train?
M: Ah, that’s a good question. In the morning, I just sit in comfort and read the papers to catch up with the news. On the way home at night, I relax with a good book or chat with friends or even have a game of bridge.
W: I suppose you know lots of people on the train now.
M: Yes, I bumped into someone I know on the platform every day. Last week I came across a couple of old school friends and we spent the entire journey in the bar.
W: It sounds like a good club. You never know. I may join it too.
