What is the woman suggesting?

M: What type of clothing should I take when I go to Sweden?
W: Some friends of mine were there last year and they said it can get pretty cool at night, even in the middle of summer.
M: Maybe I’ll pack a few sweaters then.

M: Can we take an alternate route? It’s rush hour and I have to be at the airport by ten.
W: I do this every day, sir. The traffic gets lighter after this junction. Don’t worry.
M: I knew I should have set the alarm clock earlier.
