Ha ha, yes I could write a tips post about dialogue (if I had the time, maybe next month) as it was my Achilles heel at university and so the writing tutors used to always focus on drumming some hard and fast rules into me... as much as that was possible. 

The upshot is that I've developed a very considered approach to dialogue now as I know I can fall into old habits if I don't watch myself. Glad you enjoyed the character descriptions. I went for a 'mean ladies of LA' theme 🤣
