I write haphazardly. I always have plots fighting to get down on screen, and several stories going on at once.
So because of this (work & far too many interests & hobbies) my stories take time to write. For that I apologise because I'm guilty of something makes me impatient with other writers - but in saying that, I mean it as a compliment because I along with other fans are anticipating the next chapter.
Sometimes I do forget (or get very busy & don't get around to adding new chapters), so I do appreciate a reminder from time to time.
