Now that people communicate with one another primarily by social media, letter-writing has become a lost art. The greatest casualty may be our growing inability to find words that precisely communicate our feelings and emotions. Why else the need for that burgeoning catalog of emoticons to supplement our written correspondence? A smiley face. A snarky face. A heart. A thumbs-up. But when the world stimulates your curiosity; when your state of not knowing leaves you restless; when your existential angst overflows; sometimes you just have to write a full-up letter to somebody.
