Please, please stop writing “based off of” in your papers. It is “based on.” Based on!
“You can build a structure around a center, but bases go on the bottom of things, so you can’t base something around something else. Similarly, you can build something off of a starting point, but you can’t base anything off of anything. Something is always based on something else.”
Seriously, stop the insanity. And if that’s not enough, I’m making it a deduction from here on out. Arrgh.
