You kindly tell me my absence very sensibly affects you, and that your only consolation is in conversing with my works, which you frequently substitute in my stead. I am glad that you miss me; I am glad that you find some rest in these alleviations. In return, I read over your letters again and again, and am continually taking them up, as if I had just received them; but, alas! this only stirs in me a keener longing for you; for how sweet must her conversation be whose letters have so many charms? Let me receive them, however, as often as possible, notwithstanding there is still a mixture of pain in the pleasure they afford me. Farewell.
