The Adventures of Mr Brain
Brain has too much time to think right now. But rather than thinking important, useful and intelligent (preferably dissertation-related) thoughts, brain has decided to short circuit and spend its days in a state of nervous paranoia convinced that nobody likes it and that the best thing it can do is to sit its owner on a bench and force her to stare inanely at a tree for several hours. Brain is getting itself in a state over nothing. Brain is referring to itself in the third person, which is also a little worrying. Brain must try harder to act normally, or alternatively, stop at home and let its owner go and have a nice weekend in London without it.
