This also relates to a topic discussed by Kevin Rhea on the “Shy and Free” website. Rhea claims that people who are shy consider themselves to be shy because that is the only part they allow themselves to see. Shy people are so consumed with being shy and trying to triumph over shyness that they do not realize there may be other parts of themselves that are open and outgoing. I relate to this theory as I realize when I am with certain people that I am outgoing without caring what people think of me. When l am around new people, I forget that I am capable of socializing well and I revert to my quiet self. This brings up the interesting question of whether in fact all of me is shy, or only some of my selves.
