If at First You Don't Succeed

Abbie: "I want a cookie."
Me: "No. You can't have a cookie."
Abbie: "I want a cookie for Cookie Monster."*
Matt: "No. We don't have any cookies. We have zero cookies in the house."**
Abbie: "... I want Goldfish."

*Abbie received a Cookie Monster doll for Christmas. By "Abbie" I mean "her brothers," but the boys don't have a sense of property yet, and Abbie has the sense that everything she sees is hers. Abbie likes "feeding" him cookies, and eating the leftovers.
**This may or may not be true. Yes, I've resorted to lying to my child because it's easier. I have no regrets.
