You must learn in life to take things more lightly, my dear. The world is always changing. Learn how to allow for it. Someone makes a promise, and then they break it. A play gets good notices, and then it folds. A marriage looks strong, and then they divorce. For a while there's no war, and then there's another war. If you get too upset about it all, you become a stupid, unhappy person--and where's the good in that?
