So, this is it - the big one.
Have been 'simmering' the planned story in the back of my mind all week. Sat down to start this morning and spotted some notes I had made about another possible story. Began playing with that a little and out came the words - don't know how many yet, the day's not over. So maybe I'm not writing 'Let Me Out', the original plan, maybe I'm writing 'My Sister Sue', the intruding story. Maybe I'm writing both. We'll see.
