I'm reminded of a quote from Seneca's letters to Lucilius, also circa 1st century CE:
> Thank you for writing so often. By doing so you give me a glimpse of yourself in the only way you can. I never get a letter from you without instantly feeling we’re together. If pictures of absent friends are a source of pleasure to us, refreshing the memory and relieving the sense of void with a solace however insubstantial and unreal, how much more so are letters, which carry marks and signs of an absent friend that are real. For the handwriting of a friend affords us what is so delightful about seeing him again, the sense of recognition.
