miss spacey, that's fine, i am sure you're thesis will be fine, i wouldn't worry too much about the originality of your work. as long as you make it into a nice easy to understand story. you'll be fine!
i have a few more hours till i have to email my results to my supervisor. which is good, because i can just forever keep working on it, and might end up in the wrong direction. so better to send it than keep working on it...sometimes you just have to let something go!
