I don't know anything about sport and I'm not accussing the girl of anything. I'm just asking a question that I'm hoping someone with more knowledge can answer. Is it possible to improve a personal best by 5 seconds in one go? I ask because this appears to be the cause of the controversy.
Is it rude to not finish a book club choice that was selected by someone else?
