Stop screaming mommy!

Tonight the kids were eating and Sam had eaten about a fourth of his food and got off his stool and said, "I done!"  I raised my voice a bit and told him he was not done and to get back up in his chair and eat more of his food. He looked me in the eye and said, "Stop screaming mommy!" I lowered my tone and said, "Ok, Sam you need to get back up here and finish your dinner." He said, "Ok mommy!" And hopped back up and continued to eat. I just couldn't believe it when he looked and me and said, "Stop screaming mommy!"  At least someone's keeping me in line.
