The Nerve!

So I'm driving and from the back seat my son is mumbling something. So, I say I can't understand your words. this little man in a booster seat and in a hat with floppy ears and only 3 adult teeth in his mouth, sighs and in an exasperated voice says "It's always going to be the same" I can just hear him shaking his head as if I'm getting on HIS nerves! The nerve! The he proceeds to say it very slow like I'M slow!
