Stupid Stupid Stupid...

Yesterday I received my textbook for the class, and I was sooooo happy it came on time!
When I got to class, I flipped it open to the contents page, and...it.was.very.different. I ordered the wrong edition.

So. I immediately ordered another one, the right one, and mailed this one back. Hopefully it will arrive soon.

Stupid. Stupid. Stupid.
