The "car way" of telling how far the relationship is: -- Trying to impress the woman: unlocks and opens the door, waits for her to get inside, closes her door behind her -- Dating: the guy unlocks her door and then goes around to his side to get in -- Engaged: The man opens his door leans over and unlocks her door and opens it. -- Married: The man gets in to the driver's seat, unlocks the doors, and says "Aren't you getting in?"
