Cracking the Parental System of Encryption

Like all parents, we spell words when we don't want Grace to understand what we're talking about. It has always flied over her head. But since she is studying her letters at kindergarten, she's drawing associations now. Yesterday when I spelled a word out loud, Grace was indignant. "I can't understand what you're saying when you spell it," she complained. So our system of encryption is going to collapse; the writing is on the wall. Grace is now aware that her parents employ subterfuge, and she will soon unlock the secrets of spelling. And of course we can't come up with another system, since Grace is a language sponge and learns language much faster than we do.
