There is something in LHL's smile that looks unnatural. Look closely at the corners of the eyes, sometimes it looks more like a grimace than a smile. It seems to indicate he feels uneasy or forced when meeting people. Most likely he is a born introvert, more suited as a Math Professor.
rubbish to say that this guy is an introvert would mean he displays a certain amount of inhibition,this guy displays no inhibition or subconscious restrain at all when he grins goofily with unabashed pleasure when taking selfies with najib or his fans or himself.this guy is not a introvert,hes a species of a different sort,something that does not understand social cues at all and does not understand how painfully lame and corny his jokes are nor have a sense of embarrasement at the things he say.
if u read many of his letters and articles and listen to many of his speeches,u will notice something chilling and errie,this is a guy who does not understand the value or concept of human relationship and social norms,his letters and speeches are totally alienating and textbook and methodical and theoretical.hes like a robot or autistic savant that cannot sympathise or empathise or simply does not understand other human beings' feelings or its real actual human lives his dealing with and not theoretical models.sometimes his replies are so bizzare it feels like either hes forced to lie and fabricate the truth or he simply just does not comprehend what his doing or thinking wrong.having poor introspection and failure to look at oneself and reflect on how one's words and body language and mindset is having an impact on others is a sign of low eq.in any other country,LHL would never make it as a politician let alone the Prime minister.
