Don’t be ‘two faced’ = too many people wear psychological masks ie look happy when are unhappy or visa versa to act the way they perceive that their workplace, family or friends etc want them to act and look ( OK if you have a job working with the general public, you’re expected to look HAPPY to help, as it’s a workplace requirement ) but don’t continue this pretence into your social life too ( its not psychologically healthy to do that in my opinion !! )
