But I thought I'd share as a by the way that I think perhaps part of my inspiration for my idea may have been the novelty of the phrase "Watch your step" involving females. I've told Caroline before that whenever I come across it in books and television it's usually in the context of males saying it to each other. It's very seldom you see female characters saying it too each other and the sheer novelty may have inspired me.
Then Caroline said she thinks it's probably the same in real life as well. Most women seem more inclined to say "Be careful" to other women when looking out for each other's safety and I found that really intriguing indeed.
