something sad but also kind of sweet ive noticed about human trait mirroring (i.e. seeing someone regularly preform a physical or verbal action and adapting it as your own) is that even years after a person has stopped being in my life theyve still left pieces of themself within me. i still smile and wave like my childhood best friend did. i still pull my shirts up to cover my face when im embarrassed because my favorite college roommate did that. ive learned how to be a human being through all those around me, and those after me will likely learn the same way too.
