We find ourselves in that situation where we want to believe, we want to think we're the exception, we want to think we can change someone or tame a lion or make a bad guy good or something like that but 9 times out of 10 we end up looking back going, "Oh, shame on me, should've seen that one coming!"
But it is a blessed provision of nature that at times like these, as soon as a man's mercury has got down to a certain point there comes a revulsion, and he rallies. Hope springs up, and cheerfulness along with it, and then he is in good shape to do something for himself, if anything can be done.
