You’ve just popped into the bathroom before class to straighten your bow-tie, smooth your shirt, and comb your hair. You pat your pocket to make sure the keys to your fixed-gear bicycle lock are still there and pull the MacBook from your leather bag.You’re looking très suave as you flick your hair and cast your eyes around the lecture theatre. You smile quietly as you realise you’re dressed better than anyone else, but quickly straighten your face and look serious and brooding when you realise you’re smiling.
