People smile for all kind of reasons - not all of them good. Smugness, embarrassment and fear can all cause smiles. Can you recognise which is which?
An open mouthed smile, where the lips are stretched and the teeth are on display, exudes confidence, warmth and a positive energy. ‘This kind of smile goes beyond just showing friendliness, it could be to show real excitement about something or a laughing smile, showing that you find something really funny.’ says Jean. If this type of smile is also accompanied by crinkly lines around the eyes, called ‘Duchenne lines’.
张开嘴的大笑，嘴唇向外扩张露出牙齿，这样的笑散发出自信，热情和积极的能量。珍说:“这种笑不仅仅是表达友好，也有可能是对某些事情很兴奋或者发现一些很有意思的事情。”如果笑的时候眼睛周围有皱纹，我们称之为“鱼尾纹”。
This is one of the most common types of smiles and can portray a range of different emotions from shyness to fear.
