In many ways, I close myself off to life in all its fullness.
I close myself off to others, as a form of self defense.
It happens to all of us. When you left yourself open in the early part of your life, you likely would get hurt from time to time. That pain taught us to close ourselves off in different ways: don’t let others in, use humor to keep some distance, hurt others before they hurt you, back away from anything new, and so on.
I close myself off, and miss the world. I miss out on life when I do that.
