I don't care how old you are if you are to be left alone her parents should have contacted someone to let them know she was alone I have very strong feelings on this due to some back experiences when I was younger and no matter how old you are not safe I am sorry if I am scaring you but come on people parents leaving their kids alone just does not float my boat I am sorry they should not have done this. Yes she did fine calling the police and well done but really what were they thinking such a stupid idiotic thing to do as for the realtor - well will not say anything on that one....... No one should have access to your home - no one only family.
