Too Many Textbooks

Okay, I'm confused. Very very confused.

I just answered a knock on the door to find a package on the porch, textbook-sized. I thought, "Wow, that book that Seth sent sure got here quick. It doesn't look like the sort of packaging he would have used, though...." And I was right on that count -- it wasn't from him. But it was a physics book -- from the people that were supposed to send it to me originally! So I guess they were right in their email, though still rather rude. But now I'm wondering who on earth sent me a second differential equations book -- because it obviously wasn't this company, and it wasn't the one I ordered it from -- the two came in completely different packages from different places. Unfortunately, I didn't keep the packaging from the first math book I received; that would have been smart, but oh well. But I just got my credit card bill in the mail, and I was only charged for one math and one physics book. So where did the other one come from? Because now I definitely have two differential equations textbooks, and very soon I will have two physics textbooks as well, when the one that Seth sent arrives in a couple days. Aaack! What am I supposed to do with them all?!!!!

I also got more Chinese herbs in the mail from Mom. Yay for Chinese herbs! I'm feeling much much better now -- I woke up this morning feeling more normal than I have for a week, so I think I might actually make it through school today (though I'm not looking forward to my physics test). Got to get back to homework!
