nah. socializing is performing by necessity.
"being myself" would entail picking apart people when they say silly/ignorant things regarding religion, science, etc. it'd be interrupting people and explaining how their favorite TV shows are full of holes. how their prattle about celebrities speaks to the emptiness of their heads. it'd be playing the devil's advocate when nobody is looking for a balanced discussion. it'd be going on long monologues on various topics. these are not endearing traits to have. i know that i wouldn't want to be around such a person for long.
maybe this is why social interactions can't be relaxing for some people. once you know that being yourself and "relaxing" is extremely grating on other people, you know to keep it tightly under wraps, which circumvents any relaxation in social situations.
