Disagreement of Mrs. Beaver and the others in Chapter 10?

The only disagreement I see in Chapter Ten is Mrs. Beaver's ignoring her husband's pleas to leave immediately, while she packed sacks for them all.

Now we must go back to Mr. and Mrs. Beaver and the other three children. As soon as Mr. Beaver said “There’s no time to lose,” everyone began to put their coats on except Mrs. Beaver, who started packing sacks for them all to carry.
