Lighthearted.
Sat on the train and the woman sat opposite me is having the loudest conversation with her friend. Which I don't mind. Her friend keeps making her laugh. But she's not even real laughing. She's fake laughing. One of those really loud, long obnoxious laughs, one of those cackly high pitched fake ones that makes your ears bleed.
I fear I must either punch her or move seats.
