A boy and girl of the modern variety were dating and things were getting serious. As part of their dates they would sometimes learn Daf Yomi. But the boy fell behind [ya know - finals...] and ultimately the girl dumped him.
She explained that she couldn't marry him because they weren't on the same page.
Moral: Don't date your Daf Yomi chavrusa [or don't learn Daf Yomi with your date].
