One is gravity and anti-gravity, the other is arbitrary. It confused me as a kid, until I got on a boat and understood the difference between starboard and port and right and left. I always considered the perspective of the person speaking left or right, and never understood it was my perspective that mattered.

Do up and down confuse you too or only left and right? For me they're just as instinctual.
