Do *YOU* have a billdew?

In my mail preview I saw that we were supposed to get a letter from BYU-Idaho today. Usually that's because we've missed some charge on Rachel's account. Here's the thing: we pay tuition because it's pretty obvious when that is due, but then sometimes her courses will have textbooks that they will automatically charge us for her to use...at random points in the semester. Like we will check and check and check...and then we'll forget to check for charges. And then they'll charge us and send us a letter in the mail saying, "Hey! Pay for your textbooks already!"

It's fine. 

So I walked down to her room and said, "Hey, do you have a bill due at BYU-I?"

And she goes, "What's a billdew?"

And I was like, "You know...like...when you have a bill that you have to pay at a certain time and..."

"Oh!" she said. "I thought you were talking about a thing called a billdew. And I was like, I don't even know what that is..."

And I said, "I don't know what a billdew is either, but this does not bode well for sending you out into the world..."

"Hey!" she said.
