I'm writing this as a reminder, a prod to put down what I'm thinking. I tend to mull over my thoughts, like you'd pour water over a pile of sediment. What ends up at the bottom is a solid set of words which I then can write down. Before that, it's muddy water with thoughts floating all about, nothing concrete. I have to get the thoughts settled and gelled. Then I can write a solid, coherent piece about what I'm feeling.
Just a preview: how some friends can understand, and how some just can't.
