Hello? Is someone there?

Did you ever have the dream that you're in bed and you hear the sound of another adult in your home even after your husband has left for work?
Yeah, then I realize that it's not a dream and it means that either a) someone has broken into my house and is trying (in vain) to find something valuable to steal, or b) Andrea has yet again answered the door and let the person wander on in.
Either way, I'm still in bed, undressed, and clueless as to whether this person is friend or foe.
