33.

You know when you reach for a pencil, botch up, then realize you’ve accidentally written in pen? Then you rummage for more paper but discover, of course, the last sheet’s the one you’ve butchered with ink, and there’s still no pencil, and now you have an ultimatum to face? I’m now confident time travel adheres to the same principal. So if you’ve found this apology, Future Earth, please take note of the eraser marks.
