Dexter told Delilah that he knows a really fun game to play with your parents. He calls it "Shutter Dodge " To play you need to wait until you see the camera come out. Just when your Mom or Dad presses the shutter button, do one of the following things: make a funny face, blink, turn around and show them your other end, decide to take a bath or stick your tongue out.
This game can last for a long time because they don't like to give up until they get a good photo. If you get tired, just plop down and go to sleep and let them take a picture of you sleeping.
