Read it through once

"Yes; it's late, and I'm _so_ tired." Jo's voice was more pathetic than she knew; for now the sun seemed to have gone in as suddenly as it came out, the world grew muddy and miserable again, and for the first time she discovered that her feet were cold, her head ached, and that her heart was colder than the former, fuller of pain than the latter. Mr. Bhaer was going away; he only cared for her as a friend; it was all a mistake, and the sooner it was over the better. With this idea in her head, she hailed an approaching omnibus with such a hasty gesture that the daisies flew out of the pot and were badly damaged.
