A little tip from me to you: The key to writing Moody's dialogue is to remove all unnecessary pronouns and a couple of the necessary ones from his speech.
5. Speaking of which: kids, if you're old enough to be in the store alone like grownups, you're old enough to get tossed out on your asses like them. I don't like you, I don't think you're cute, and I will stab you in the eyes with a barbeque fork if you knock over one more candy display or yell one more question into my face when I'm trying to deal with an adult, paying customer. Parents, babysitters, and suchlike: if you can't make 'em behave in public, you shouldn't take 'em out. Get a cave somewhere.
By the way, "stop crying or I'll give you something to cry about" is an excellent child-rearing tool that sees far too little use in society today. --funwithrage in this post.
