Faking it

You can pretend to be happy, angry or sad, just by changing your expression. But, for example, when you fake a smile it is very hard to use all the muscles you use when really smiling - especially those surrounding the eyes. Your true feelings can also show through your posture, body movements and tone of voice. However, most people will take others at face value, and do not realise when emotions are faked.
