心理学家莫妮卡·摩尔的研究论证了一个常识：它可以在拥挤的房间里吸引别人的注意力，“眼神交流和保持微笑”可以展现你的亲切和自信。

It can catch someone's attention in a crowded room, "Eye contact and smile" can signal availability and confidence, a common-sense notion supported in studies by psychologist Monica Moore.

一个微笑，扶着打开的门，一个手写便条，一句亲切的话语，等等，可以一直例举下去。

A smile, a door being held open, a handwritten note, a kind word, the list can go on and on.

社交是个大大的微笑，一个大大的微笑除了牙齿什么也不是。安心并亲切些吧。

Sociability is a big smile, and a big smile is nothing but teeth. Rest and be kind.
