§6.16.1si mihi tecum non et multae et iustae causae amicitiae privatim essent, repeterem initia amicitiae ex parentibus nostris, quod faciendum iis existimo qui paternam amicitiam nullis ipsi officiis prosecuti sunt.
If there were not many and just grounds of friendship between you and me privately, I would trace back the origins of our friendship from our parents, which I think should be done by those who have not themselves followed up their paternal friendship with any services of their own.
itaque contentus ero nostra ipsorum amicitia.
Therefore, I shall be content with our own friendship.
cuius fiducia peto a te, ut absentem me, quibuscumque in rebus opus fuerit, tueare, si nullum officium tuum apud me intermoriturum existimas.
Relying on this, I beg of you to protect me in my absence, in whatever matters there shall be need, if you believe that no service of yours will ever die out in my memory.
vale.
Farewell.
