Used

Are you sure she's your girlfriend and not your study buddy?

Or maybe you're the tutor-for-sex?

Make sure you're getting paid before the term ends. You wouldn't want to get stiffed, so to speak.

sounds like you're in great shape for no nut November. you should thank her for being so helpful

does she call you in other cases?

that ain't your girlfriend bro.

We all deserve someone who prefers our company over all others...whether that is a human or a pet lol, but it's true. Everyone has a fav person, so who's yours when the chips are down? THAT is what you're looking for...think back to before you met her. Everybody forgets that they existed just fine before they met 'THE LOVE OF THEIR LIFE'....but they did, they existed :)

not to be a pessimist but maybe she just has has alot of homework
