From Little Women by Louisa May Alcott

"Is she? By Jupiter, I will, if I only get the chance!" cried Laurie, sitting up with sudden energy. "I ought to be satisfied to please Grandfather, and I do try, but it's working against the grain, you see, and comes hard. He wants me to be an India merchant, as he was, and I'd rather be shot. I hate tea and silk and spices, and every sort of rubbish his old ships bring, and I don't care how soon they go to the bottom when I own them. Going to college ought to satisfy him, for if I give him four years he ought to let me off from the business. But he's set, and I've got to do just as he did, unless I break away and please myself, as my father did. If there was anyone left to stay with the old gentleman, I'd do it tomorrow."

Laurie spoke excitedly, and looked ready to carry his threat into execution on the slightest provocation, for he was growing up very fast and, in spite of his indolent ways, had a young man's hatred of subjection, a young man's restless longing to try the world for himself.

"I advise you to sail away in one of your ships, and never come home again till you have tried your own way," said Jo, whose imagination was fired by the thought of such a daring exploit, and whose sympathy was excited by what she called 'Teddy's Wrongs'.

"That's not right, Jo. You mustn't talk in that way, and Laurie mustn't take your bad advice. You should do just what your grandfather wishes, my dear boy," said Meg in her most maternal tone. "Do your best at college, and when he sees that you try to please him, I'm sure he won't be hard on you or unjust to you. As you say, there is no one else to stay with and love him, and you'd never forgive yourself if you left him without his permission. Don't be dismal or fret, but do your duty and you'll get your reward, as good Mr. Brooke has, by being respected and loved."
