Necessity Is The Daughter Of Incomprehension

(A mom and daughter come up to my checkout. As I ring up the items, the mom notices the novelty pens by the register.)

Customer: “How cute! Do you want one, honey?”

Customer’s Daughter: “I don’t need one.”

Customer: “That’s not what I asked. Do you want one? How often does your mom say that?”

Customer’s Daughter: “I don’t need one.”

Customer: “Look, they light up! Which color do you want?”

Customer’s Daughter: “Doesn’t matter. I don’t need a pen.”

Customer: “Choose a color or I’ll choose for you!”

Customer’s Daughter: “Mom, you’re wasting money!”

Customer: *to me* “We’ll take the blue one.”
