Never answer anyones questions under pressure.
People in life will try to make you feel like you are obligated to talk to them....you are not.
If you are in a bad situation. Tell people to get away from you and walk away....if they walk after you asking questions tell them to stop STALKING you and call them a weirdo....
Let them know that you find them to be CREEPY and to stay away or you will defend yourself.
Never "explain" your beliefs to people that want to harm you
I have used this technique a few times.....by walking away from people and tell them to stay away it gives you the right to defend yourself if they refuse
