One more thing: If, by chance, you are dealing with someone who is... well, let's just say 'uncultured', chances are, you're going to have to do most of the work I don't know her, personally, so I can't be sure but based on the behavior she put her granddaughter up to, I'm guessing this is the case. No reasonable adult would have a child fight their battles. That's just mean to the child.
