Peter and the Tim Tams

We generally have a little dessert after our supper here.  For dessert we generally each have one Tim Tam (a popular Australian cookie.)  Peter has recently started joining us at the supper table and sharing in dessert.  He has fallen head over heals in love with Tim Tams.  At the first sound of the crinkling package his eyes light up and he kicks and squeals and does everything he can to communicate his enthusiasm.  I'd be worried except that he acts the same when he sees fresh strawberries or watermelon.
