Fresh veggies

Kevin bought some vegetable plants and put them in bigger pots yesterday.  He put them over by the wall where they would get some sun and some shade, and then put a little fence around them to protect them.  But did he really think that little fence could keep me out?  I went right up to them, stuck my head over the fence and knocked it in, and I ate one of the squash plants.  It was yummy, so why are they mad at me?
