user: Julia prepares a gift box for her son, Steven, under the Christmas tree. She wants to prank Steven. She fills the gift box with tea leaves but labels it coffee beans, written in clear large letters. A few hours later, Steven comes down the stairs and finds the gift box under the Christmas tree. Steven does not open the gift box and does not look inside. Steven reads the label. A cousin calls Steven and tells him that the gift box has tea leaves in it, and that he should ignore the label that says "coffee beans". Steven believes him cousin.

assistant: He opens the gift box and looks inside. He can clearly see that it is full of coffee beans.
