In a personal side note, Amy bought creamy peanut butter at the supermarket today. Even though she likes chunky. So it appears she can only hold out against my considerable charms for 10 months.
Oh and if you haven't tried generic peanut butter, don't start. Seriously. A lot of generic products are just as good as the name brands. Peanut butter is not one of them. We bought some generic chunky 10 months ago and we had to stir it before we used it because it would separate into peanut oil, chunks, and God only knows what else. Totally disgusting. I wish I could describe it more fully so I could better gross you out.
