How does the woman usually go to work?

M: Lisa? Hi!
W: Hi, Ned.
M: Don’t you usually drive to work?
W: Usually, but not in bad weather.
M: Why is that?
W: The traffic gets a lot worse when it rains or snows.
M: I always take the train.   It’s a lot faster for me than driving.
W: It’s faster for me, too, but the time isn’t always convenient.
M: Yeah, but think of all the things you can do on the train—read a book or the newspaper...
W: Or answer my email... No thanks’. My workday is long enough already.
