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.

W: Do you know where the key to the closet is?
M: I believe Nancy left it on top of the filing cabinet next to the water cooler.
W: Would you remind her to return it to the key holder?
