Child comment is probably right, "asymmetrical" was likely going through my mind, or some chimera of both. I mean to say that whatever humans do, their actions ("requests"), don't get a response from "nature" immediately, the "response" is unpredictable, particularly as to when it will come back. If we get a break down SS, we get no response. Request(s) -> nature impacted -> some time passes -> response comes back, but not all nice and linear, nor always what we expected. "Promises" only coming with deep understanding.
