I love this Advert because it is the best example I know of
'Reverse Body Language/NVC'.
Here the geezer is being nice to the hairdresser but using aggressive non-verbal communication to show his sister how angry he is (pretending to be) - good stuff.
In real life it is impossible to do.
When we are angry, angry NVC comes out.
When we are warm towards another we become a Palm Person, open palms used.
Here we see some great examples of Pointed Finger Person.
When we are feeling 'not ok' - be aware of how we communicate.
It is usually pretty ugly.
But at the same time you are beautiful - behaviour is only what we see.
Beyond - there is a BHP trying to get out!!!
