Yes, because if a girl has sex with you at your place, she is bound and obligated to stay the night. The ENTIRE night, even if you roll over and go to sleep immediately afterward and even if she has obligations to attend to. And if she dares to leave? Then the appropriate response is to shun her, basically. Ignore her attempts to apologize and subsequently ignore her texts. I mean, **** her. She makes you wait five dates before putting out and then, like, just leaves and goes home after telling you she had a really great time?! What the ****!
