I am anxious to hear from you on many points, but much more to see you in person. Restore me Demetrius's friendship,* and anything else you can that is worth having. I don't say a word to stir you up about the Aufidian debt: I know you are looking after it. But settle the business. If that is what is detaining you, I accept the excuse; if it is not, fly to me. I am very anxious for a letter from you. Good-bye.

Notes from the translator, E.S. Shuckburgh:
Restore me Demetrius's friendship—Demetrius (see Cic. Fam. 16.17) seems not to have been satisfied with Cicero's reception of him.
