I had this conversation with a student today:

Me: "Why aren't you working on your math?"

Student: "I can't! I need someone to help me!"

Me: "I'll help! What do you need?"

Student: I need the formula for a trapezoid.

Me: What kind of formula?

Student: For a trapezoid!

Me: No--what kind of formula for a trapezoid?

Student: What do you mean? I just need a formula for a trapezoid!

Me: I mean, do you need the formula for the area of the trapezoid?

Student: No, just the formula for a trapezoid.

Me: There's no such thing.

Student: Yes there is! I need to know what it is!

Me: I can tell you the formula for the area of a trapezoid.

Student: No! Oh my god. You aren't listening to me. I just need the formula for a trapezoid. I'll just wait for the other teacher. She's in my math class, and you're not, so you obviously don't know what you're talking about.

Me: I've taken a 7th grade math class once or twice. And I am very confident that what you are looking for is the formula for the AREA of a trapezoid.

Student: Oh my god, no!

(This exchange continued back and forth for a ridiculous amount of time until the student angrily got up, stomped over to his Chromebook, typed something, and pointed to it.)

Student: See! There. The formula for a trapezoid. Right there!

Me (taking a closer look): Yep. That's the formula for the area of a trapezoid.

Student: No! It's not!

Me: Look! What do you think the A stands for?

Student: Something else!

Me: I'm done with you.

Student: God! Nobody will help me!
