Jean Webster said this quote

... in spite of being happier than I ever dreamed I could be, I'm also soberer. The fear that something may happen to you rests like a shadow on my heart. Always before I could be frivolous and carefree and unconcerned, because I had nothing precious to lose. But now -- I shall have a Great Big Worry all the rest of my life. Whenever you are away from me I shall be thinking of all the automobiles that can run over you, or the signboards that can fall on your head or the dreadful, squirmy germs that you may be swallowing.
