Thanks all for your messages. She has shoulder/boob length currently and its nice and thick but just can't help wanting it longer. I have asked her to grow it out and she says yeah i'll do it but "long" in her in opinion is like barely waist length. It's the convincing to get her past the so called norm 'long hair' i.e maximum of waist length and into the more juicy regions of butt and knee length lies the difficulty. Think the idea of saying ill help care for it is a good shout.

Think the misinterpretation of what length 'long hair' is an issue thats always been around...
