tbh I think she seemed like the sort of girl who would be well-liked and easy to get on with, especially in the Cambridge environment. However her mindset before going into her 4-week stint seemed a bit off. The way she was astounded by that rock-show-award-thing they went to made me think she was perhaps very sheltered...
One thing that did very much annoy me indeed was when, after she'd dismissed every CD in the rock-chicks collection as twaddle, and was then asked 'but can you see how other people would like it?'... and she said 'no'... followed by something that came across to me like 'I think the only reason people would like that music is to look hard'... ... ... I'm not sure if that's what she meant but OHMYGOD...
I think she could have been more open-minded about it all. Every other faking-it character seems to go in wanting to 'experience' whereas she seemed to only want to achieve the goal as purely herself unchanged... I don't think the issue of her religion vs rock should have restricted her... afterall Christian Rock is pretty damn big.
She said herself she felt she'd wasted the 4 weeks, and she probably had.
