2Quilt,
I have always been a letter writer. When one tries to explain a problem the other person gets on the defense immediately. When writing, they read by themselves and are less likely not to read it. Curiosity gets to them so they continue reading. This is also proof of the goings on. The receiver of the letter is less likely to show it to someone else to get their support as it tells exactly what the problems are.
