This resonates and I'll explain why - I have always been a person who is lost in thoughts - I don't know if it is due to my introverted nature or because I prefer my world to socializing and such - but you can guess how my expression looks to others when I'm lost in my thoughts - then again it is a way for keeping people at bay (when I am not lost in thoughts) My expression tends to be cool - and that is because I am terrified of strangers approaching me because I really don't know what to say - (very shy)
