No, no, no, and also no!
It's so frustrating to come home from work, or a trip to the store, get out of the shower, or even just wake up in the morning and realize that people have been roaming around inside your house like little mice that only come out when the lights are out or you're away. Mice have an excuse...they are mice. People on the other hand could call you at home, work, or mobile, text, email, or even just yell in your general direction to let you know. Really amazing people could even give you a few minutes notice. No such luck for me...I'm clearly not dealing with rational people here.
