While cleaning Sarah's room (together).
Sarah: Look! I found a lucky penny!
Me: Oh neat! So what is luck?
Sarah: Well luck is when you wish for whatever you want and you get it!.....I always wish for more lucky pennies. And look! another one!
Me: Can I have one?
Sarah: Sure! I can share.
Me: I wish Sarah would clean her room.
Sarah: Uh oh, you said it out loud. Now it won't come true!
Me: *does the mother look*
Sarah: but..um...I'll clean anyway!
