Haha, nice description!
I'm not really attracted to the bob or other short styles in themselves, but I do like the connotation of these styles as something domineering. In my fantasies, I imagine the short-haired girl as the more bitchy and masculine one alongside her hyper-feminine rapunzel friend. Also, I feel there's something really hot about a short-haired girl telling her super-long-haired friend to "get a haircut" or "short hair would look great on you."
