Your reply illustrates my point perfectly: once you learn a system, it's really hard to see how anyone couldn't find it obvious. We reach a state of always-already, unable to go back to a point when we had no idea what that thing was, or what it meant or did. So we get annoyed (or just baffled) when people point out it doesn't make sense to them, because on some level we just can't comprehend anymore not comprehending.

Which is a fancy way to say: I'm aware it can be aggravating to have someone say, this doesn't make intuitive sense, when you've already made the intuitive leap, or at least accepted it -- because it seems obvious. But it doesn't change the fact that for someone not there yet, it's not.

And I'm just someone constantly seeking to undo the always-alreadys I find, is all.
