Jack and Jill by Louisa May Alcott

Things were not so gay in Ward No. 2, for Mrs. Pecq was very busy, and Jill had nothing to amuse her but flying visits from the girls, and such little plays as she could invent for herself in bed. Fortunately, she had a lively fancy, and so got on pretty well, till keeping still grew unbearable, and the active child ached in every limb to be up and out. That, however, was impossible, for the least attempt to sit or stand brought on the pain that took her breath away and made her glad to lie flat again. The doctor spoke cheerfully, but looked sober, and Mrs. Pecq began to fear that Janey was to be a cripple for life. She said nothing, but Jill's quick eyes saw an added trouble in the always anxious face, and it depressed her spirits, though she never guessed half the mischief the fall had done.

The telegraph was a great comfort, and the two invalids kept up a lively correspondence, not to say traffic in light articles, for the Great International was the only aerial express in existence. But even this amusement flagged after a time; neither had much to tell, and when the daily health bulletins had been exchanged, messages gave out, and the basket's travels grew more and more infrequent. Neither could read all the time, games were soon used up, their mates were at school most of the day, and after a week or two the poor children began to get pale and fractious with the confinement, always so irksome to young people.
