Cameron stands alone!!!

So last night as I was sitting on the computer I hear this shriek from Daryl calling my name out. He hit a note that I wasn't aware he had in his voice range. Scared the living crap out of me!! I jump up from the computer and run to the stairs only for Daryl to show me that Cam was standing all by himself! I was so amazed! He did it a few times so I grabbed my camera thinking he wouldn't do it again because that's usually what happens...I swear they know when I am filming...and sure enough he did it again! Wow my big boy!!!
