The tree said "Cheese!"

We finished the sandbox in the backyard and Michael enjoyed playing with the sand and his toys. He found a weed and decided to "plant' it in the sandbox, so I asked him if he was planting a "tree." He said yes, and so I asked him if he wanted a picture. He said yes, and when I came down the stairs he told me that the tree was saying "Cheese!" to have its picture taken.
