Read it through once

"I did wrong to sigh, Jo. It is natural and right you should all go to homes of your own, in time; but I do want to keep my girls as long as I can; and I am sorry that this happened so soon, for Meg is only seventeen, and it will be some years before John can make a home for her. Your father and I have agreed that she shall not bind herself in any way, nor be married, before twenty. If she and John love one another, they can wait, and test the love by doing so. She is conscientious, and I have no fear of her treating him unkindly. My pretty, tender-hearted girl! I hope things will go happily with her."
