“I should hold it up to you muck-covered and show you its dirt and danger. I should warn you to look closer until you can see how ugly it really is. I should ask you to think of inconstancy and give you examples. I should give you Othello’s handkerchief. Oh, I know I should. And I should straighten out your tangled thoughts, show you that the impulse is gray as lead and rotten as a dead cow in wet weather. If I did my duty well, I could give you back your bad old life and feel good about it, and welcome you back to the musty membership in the lodge.”
