I am a highly erratic writer as the 'scenes' that I write usually are written in my head - often when I first wake up in the morning. They evolve or play out in my head in great detail (for as long a 'moment' of silence that I am likely to get with a family of four and husband!) Even if interrupted before I can capture it right then and there- they are so vivid and 'solid' - that I can usually recapture the words and feel of the scene no matter how long it takes for me to sit down at a desk and type. But then it may be days or weeks or even months before another scene takes hold and emerges. It is highly inconvenient and frustrating but I am learning to cherish the process and capture moments better.
