This ten-second clip repeats a firm no in a rising, exasperated female voice, each refusal landing harder than the last as disbelief turns into protest. It feels awkward, dramatic and a little funny, like watching someone realise a bad idea is actually happening and trying to stop it. It comes from episode 37 of The Lizzie Bennet Diaries.
