When meeting new women, using the "Door Test" is a brilliant exercise to judge their relative selfishness. The test is very simple-just pull up right where she lives and lock both doors. Then get out of the vehicle. Bring her over to the vehicle and open the passenger door for her, let her get in and close the door. Then slowly walk around the back of the car and look through the rear window and wait for truth to emerge.
There's no subjectivity with the door test. The Door Test is simply on a Pass/Fail, Keep/Dump basis. If she opens the door, she's a keeper. One or even two failures on her part might be understandable, but any more than that indicates her selfishness and a certain lack of empathy and you need to dump her fast.
