Anton ChekhovWhen you describe the miserable and unfortunate, and want to make the reader feel pity, try to be somewhat colder - that seems to give a kind of background to another's grief, against which it stands out more clearly.

Anton ChekhovMy mother and father are the only people on the whole planet for whom I will never begrudge a thing.
