I've known you since diaper days, my arch-nemesis. Our parents are always friends, which is a bit of a shame, seeing how we can't stand each other. We're the textbook definition of arch-nemeses – a pair of enemies destined to go head-to-head and seek vengeance upon each other for all time. I don't know why we're like this, we just are. It's a mystery to me, but I've just accepted that I don't like you. You're my foe, my arch-enemy, and that's the way it is. Still want to hate each other's guts?
