The Temperature Of The Room Just Dropped

(My mom opens my Christmas present to her: an indoor/outdoor thermometer.)

Mom: “Oh, good! I wanted one of these.” *looks at my brother* “What? You have a funny look on your face.”

Brother: “Nothing. Don’t worry about it.”

Me: “We did not discuss what gifts we bought.”

Brother: “We did not.”

Mom: *opens his gift: another thermometer* “Well, I really, really wanted one!”
