I'm taking a poll in a very serious matter: What you would Do if you were in this situation? (Adults Only)

You're at a firend's house, you're standing outside aganist the wall takling to someone, suddenly a car pulls up to the driveway and you see a person reaching as if thet're getting something from under the driver's seat, they jumps out of the car screaming and yealing profanity at you, as they approch you their right hand is behind their back and thet're pointing with their left hand at you and close enough to polk you in your chest while screaming "Do We have A Problem" (repetedly) This person is angry and polking you, their hand is behind their back and they are screaming at you. Would you be afraid and fear for your life? Would you think that this person has a weapon behind their back? You back is aganist the wall, there's nowhere to run, What would you do? If you had a weapon, Would you use it? Or would you wait to see if the person has a weapon or not before you protect yourself or would you just take whats comming?
