Even while writing a letter a person sometimes puts in it what words cannot explain - and yet the letter conveys it. There may be one word written with a living thought behind it; that word will have a greater effect than a thousand pages. Do we not almost hear a letter speaking? It is not always what is written in it; the letter brings the one who wrote it to us, what mood he was in, his evolution, his pleasure, his displeasure, his joy and his sorrow. The letter conveys more than what was written in it.
