Read the quotation from The Metamorphosis.
If I didn't have my parents to think about I'd have given in my notice a long time ago, I'd have gone up to the boss and told him just what I think, tell him everything I would, let him know just what I feel. . . .Well, there's still some hope; once I've got the money together to pay off my parents' debt to him - another five or six years I suppose - that's definitely what I'll do.
