"Is north that way?"
I can't quite get my head around how speaker proximity works with direction. Like, if I'm standing due west of you, and you're due east of me, then would west be kochira, east sochira, and north and south would be achira? Or are all cardinal directions achira, since their terminal points are far from everyone?
I suppose if you were talking to Santa Claus, north would be sochira.
