There's a pause. Either she's gathering her thoughts or she's waiting for me to catch up with my note taking. I don't really care which one as I'm using the time to scribble down the end of my last thought before she starts talking again.
"You're going to have to explain why the Tower does not signify change..."
And then my mind does something like this:
.... before tuning in again to realise that what she's actually talking about is a comparison between the tower and Camelot in 'The Lady of Shallot', also known as the topic I'm writing my essay on.
I thank god that the only thing that signalled this break in my concentration was my pen pausing over the piece of paper I was writing on, before kick-starting back into note taking.
