Imagine that you are just getting home from work after a long, hard day at the office. You pull up to your house and notice that the glass on your front door appears to be broken. You immediately get that sinking feeling in your stomach as you put your car in park and turn the key to the off position. Walking toward the door, you sigh heavily as you turn the knob and it opens. You didn’t leave it unlocked, but it is unlocked now.
