A quote
You have been demanding more frequent letters from me. But if we compare the accounts, you will not be on the credit side. We had indeed made the agreement that your part came first, that you should write the first letters, and that I should answer. However, I shall not be disagreeable; I know that it is safe to trust you, so I shall pay in advance, and yet not do as the eloquent Cicero bids Atticus do: “Even if you have nothing to say, write whatever enters your head.”
