If you really want to borrow $25 from me, I will take a chance on finding out what kind of person you are.
I want you to understand right now that I will not accept any excuse—except a serious illness. If you become ill, then I will give you an extension of time—but for no other reason. If, when the debt becomes due, you tell me that you can’t pay me because you needed a new pair of shoes or a new coat or you gave the money to somebody in the family who needed it more than I do—then I will consider you as an embezzler. No, I won’t send a policeman after you, but I will write you off as a rotten person and I will never speak or write to you again.
I will tell you the reasons for the conditions I make: I think that the person who asks and expects other people to give him money, instead of earning it, is the most rotten person on earth. I would like to teach you, if I can, very early in life, the idea of a self-respecting, self-supporting, responsible, capitalistic person. If you borrow money and repay it, it is the best training in responsibility that you can ever have.
