I think a lot of people have layers to them, each one deeper than the one before, each one accessible only to a closer and ever shrinking group of people. For example, the you that people see just casually walking down the street, someone that might say hello to a stranger, is not the person your close friends and family know. I think we’re all very guarded when around people we don’t know well, and as we get to know them, and they get to know us, those layers are peeled back. I’m very introverted and quiet, but around people I know well and have known for a long time, I’m a little more animated (though not much). It takes a lot of trust to peel those layers back, because doing so exposes us to others, it lets them in. You can get hurt that way, but it’s one of the side effects of being human.
