manyak /k alpha male duno girls very easily traumatized when it comes to self security.
they will feel paranoid if they think some one is following them around even thought the person is not.

this stunt to putting the paper at the car there is not crazy to guys.
but for girls who are not that sociable or timid, this is super duper crazy stalker levels.

imagine, u as a girl who is not physically stronger than a guy, have your location known to a random male.
to further add fuel to this, the guy followed you for miles in his car to the food court u were eating at.
then put the paper there to let the girl know his presence which the girl think first, this guy can get me at any time he wants.
thus, triggering her fears.
