Here are my thoughts, take them or leave them:
I am not, at heart, a worrier. I don't have the time or energy for it. I lived in fear most of my childhood (long story) and I refuse to do it as an adult. Bad things happen. Such is life.
However, that does not mean I don't live irresponsibly. I lock my doors, stay out of bad areas at night, etc. I did that before DS, I'll continue to.
There is a registered sex offender in my town. I choose not to worry about...
