Human beings can communicate by gesture and facial expression as well as by verbal language. In the following video, at 39 seconds in BBC presenter Jo Coburn is not communicating to the viewer – the director has switched back to her before she expects. She is however working very hard on communicating non-verbally to somebody, presumably the director, with quite an extreme facial gesture.
My question to you is this – what do you think she is trying to communicate with that facial gesture, and why? It is not a rhetorical question, your answers are welcome. You need to watch the whole video for context – it’s less than a minute.
