Codster- or Codmonster?

Can someone please explain to me how the sweet child pictured above can be two such different people when the mood hits. Today, for example, we had a great morning. We worked out together and started some laundry. We did some pickup and then got in the car to run some errands. During our drive to Walgreen's (where we were to pick up a couple of pictures for a school project) he was singing his favorite Christmas song to me and pointing out interesting things. Ah, I love live with my sweet little Codster.

Then, trouble hit. The guy at Walgreen's decided I needed to wait at the picture counter for ten minutes while he did something- which I am sure was much more important than serving a paying customer in the retail industry (but I digress to an unproductive soapbox)- and my sweet Codster was more than a little tempted by the candy right at his eye level. When I refused to purchase him the jumbo box of Mike & Ikes- boom Codmonster! He started yelling at me in the store- stomping his feet and then growling (literally). Naturally, the only people in Walgreen's at 11:30 in the morning are the elderly- who were perfect parents and whose children never once needed discipline (am I digressing again?). I was very kind but firm- finally taking Codmonster's wrist and marching him out of the store. My elderly friends all had very helpful comments as I marched Cody past. Did I mention that at this point he was using his free hand to punch my leg every third step?

How does this happen, I wonder? How can this child go from singing me carols to growling at me in a matter of minutes?

Now Loren and Kalin know the truth- we aren't perfect parents, sigh. And I will continue to try and raise Jekyll and Hyde.
