Totally Worthless

So I sent my aunt the dates I would need to go to Ohayo, the airport code, and a rough estimates of the times I would like to show up and leave. Two weeks pass. Today I get a call.

"Yeah, I'm about to make the reservations for you to go to Cincinatti-"
"Columbus."
"Right, whatever. But Unc and I decided you can only stay for two days."
"Why?"
"We're paying for your hotel, and we don't want to pay for all four nights."
"No, you're paying for my plane ticket. I'm paying for my hotel. And it only costs $100 for all four nights."
"Oh. Well, you may have to come back to STL on the 16th."
"Why?"
I never found out why. Instead: "When do classes start back up? Will you be missing school?"
"No. Look, I gave you the times and the dates. Now PLEASE make the reservations?"
"How will you get back to UPS? What if you get in late? When do classes restart?"
"The 18th. And I'll take the shuttle back."
"Okay, I'll make the reservations."

...

And I just got a call back.
"When do classes end?"
"I have to be out of the dorm by noon of May 14th."
"Will finals be over by then? They'd have to be."
I pause, since she answered her own question.
"So will you have a place to sleep on the 13th?"
"The dorm closes at noon on the 14th. I would assume so, unless my dorm explodes."
"Oh, noon on the 14th? I didn't know that."
