P's start out at a early age....the harm those around them and are cruel to pets, small children.   They also like to start fires and steal, and lie.   They cannot be trusted safely to do anything unless they are watched.   The difference between troubled kids and P's is the constant attack on the weaker creatures of this earth and the fires.  They show you a face of sweetness and light and as soon as you are out of sight the real P comes out....so watch her closely and get long term professional help...one that deals with troubled children.   They will spot her sooner or later and if she is a P it will show.
