Your Argument Doesn’t Hold Water

(At the college bookstore where I work, students can sell their books back for cash at the end of the semester.)

Me: “I’m sorry, ma’am, but I won’t be able to buy your textbook back because of the water damage.”

(I flip through the book’s crinkled, sticky pages.)

Student: “Oh, it’s okay. It’s not water damage, it’s humidity. I went on vacation to Missouri and it was humid.”

Me: “I still can’t take your book back because I cannot sell this to another student in this condition.”

Student: “But it’s not water damage! It’s humidity! Humidity made the pages stick together!”

Me: “Ma’am, what is humidity?”

Student: “Water, duh!”

(There’s a pause while the wheels begin to turn in her head.)

Student: “Oh…can you help me find my other books, then?”
