Dating is absolutely the most soul-grinding thing we do as people. You go on a million dates with a million people, and each time you find out you have some kind of fundamental disagreement that means the whole thing isn't going to last. (For me, that's dating someone who doesn't like the last episode of Lost. "It was a character show — of course they weren't going to answer all the mysteries!" I've screamed at many beautiful and kind women who loved me.)
