Overheard: spy

Tayv: "Hey Mom, wanna play spy?"
Me: "Um, maybe. I'm just going to do something for daddy's b-day then I was going to try to get your presents together for your b-day."
Tayv: "Oh, ok. I'll probably spy on you."
Me: "hahaha, no I don't think that's a good idea."
Tayv: "Oh, I don't think I'll see anything because I'll be hiding behind a wall."
