The gentleman has nine cares. In seeing he is careful to see clearly; in hearing he is careful to hear distinctly; in his looks he is careful to be kind, in his manner to be respectful, in his words to be sincere, in his work to be diligent. When in doubt he is careful to ask for information; when angry he has a care for the consequences; and when he sees a chance for gain, he thinks carefully whether the pursuits of it would be right.
