Mimicry

I was walking around the other day, when I started to think about how many times when you are in you're comfort zone, the way you dress, talk, express, move and walk change in a way that somehow you see you're self blending in the social environment.
Is this because we want to belong to this social organism or is just because that the way human beings are designed.
The idea of having to blend yourself in the society surrounding you is a little bit scary if you think about it.
Because that means that you losing a part of your self just to fit.
But what could we do to avoid losing our selves, This is not a self-experience, this is what I recall watching people do to save themself from society.
* Dance the way you want when everybody else is drunk, in that way they won't remember.
* Singing the nasty or the most annoying songs that you like, when you're alone at your house
* Walk-in funny unique ways when you feel happy
* Laugh, scream, cry, jump
* Write emails to yourself with the critics of the people around.
Anymore ideas ? ? ? ?
