I know of an absolute idiot of a woman that refuses to go anywhere after dark. She is in her fifties and has been this way her whole life apparently. I don't understand people who are afraid to go about their business and leisure. If something is going to happen, it will happen no matter where you are.
There are people who've been killed walking down the street, at the grocery store, while exercising, at parties, at churches, at work (where most people spend the majority of their time), while driving, on vacation and while at home just to name a FEW.
All one can do is prepare themselves, be aware of their surroundings, and LIVE their lives. In an attempt to keep this clean, stuff happens, no matter what time of day it is, whether you are at home, etc. Being afraid robs you of experiences and opportunities to enjoy yourself and those who are important to you. This is what makes life worth living for, I don't know why some people treat their lives like they are doing time in jail, afraid to truly live and letting life and time pass them by.
