ANY GUESSES?

While we still wait for either Rabbit or Dan to win the Surprising Fact Contest (a few posts below). I thought I would share with you another fact about me. And while it's not 'surprising' per say I imagine it is odd. I almost always have two jars of peanut butter in my kitchen opened at the same time. As soon as one of them runs out I open yet another so there remains two open. They are the same brand and style in every way. And it has nothing to do with Aspen or anyone else in the household. So, would anyone have a guess as to why this would be? What is an 'odd' habit or fact about you? Please share.
