MacOS Scroll Direction: “Natural” or “Regular”?

My girlfriend and I are in a fight right now about which scroll direction is proper.

I don't like the natural scroll direction, because the laptop is not an iPhone or iPad. I view the track pad as a mouse, and the "Natural Scroll" feels backward to me. She says that the "Natural" scroll matches up with all the other devices we use. Which for me is just an iPhone, and a laptop.

HN: Which way to you scroll?? Help me resolve this debate.
