*(I hear this stupid conversation between two classmates sitting next to me.)*

**Classmate #1:** “We’re going some geology!”

**Classmate #2:** “Do you even know what that means?”

**Classmate #1:** “No.”

**Classmate #2:** “I think it’s the study of life.”

*(I’m in algebra class and we’re learning a rather difficult topic.)*

**Girl Across the Classroom:** “Man, you either get this, or you don’t, and I’m in the middle.”

**Me:** **facepalms as I realize the impossibility of this statement**

*(I buy some leggings that are 50% off of the original price of £8. There is something wrong with the tills, so the cashiers have to work stuff out on calculators. I am dumbfounded when the girl starts using her calculator to figure out 50% of £8.)*

**Cashier:** “Um… That’s £7.84, please.”

**Me:** “No, that’s not right.”

**Cashier:** “50% off is £7.84.”

**Me:** “No, it should be £4.”

*(The cashier takes her calculator and shows me how she worked it out. She divided 800 by 50 and took the answer, 16, off the £8.)*

**Me:** “That’s not how you work out percentages. 50% is half; half of 8 is 4.”

**Cashier:*** *pauses* *“I think you’re right, actually. Sorry. That’s £4, please.”

*(I overhear this conversation between two four-year-olds at snack time.)*

**Child #1:** “Did you know that five plus five is ten?”

**Child #2:** “Oh, yeah? So, you know what one plus one is?”

**Child #1:** “Um, I don’t know. I only know that five plus five is ten.”

*(I am wandering around the school with some friends after lunch.)*

**Friend #1:** “I’m so not ready for my math test.”

**Friend #2:** “What period do you have math?”

**Friend #1:** “My math class is next period.”

**Friend #3:** “Uh-oh, we’d better quiz you.”

**Friend #2:** “What’s 7+63?”

**Friend #1:** “69.”

**Me:** “Are you serious?”

*([Friend #1] realized what she said and immediately face-palmed.)*
