Attack of the toddler.

I know, this picture looks nice enough. A is playing in his shop, ringing something up, it is organized and stocked with groceries, toys, and bags. He is happy. But lurking, the two year old plots his next move (Jaws Theme Song Here and the blurry arm to the left). Suddenly, whoosh, he attacks. The shrieking "MEEEEEEEEEEEEEE DOOOOOOOOOOOO" (yes, this was edited, my 4 year old corrected me) gives the shopkeeper warning, and he turns to the sound, just as the rushing toddler reaches him. After a brief struggle with the bar code scanner, the shopkeeper concedes the hand-held device to the wild and insistent 2 year old, who replaces him as shopkeeper.
As a final warning, and to establish that he is in fact the shopkeeper, the toddler gives one last shriek, "MEEEEEEEEEEEEEEEE DOOOOOOOOOOOOOOOOO" ...
...before happily scanning wooden items and placing them in canvas bags. The former shopkeeper, now reduced to the shopper, graciously accepts the bag, hands over all of his money as payment, and sings a song as he wanders off to the next thing. The ripples settle, and both are merrily playing, as if the toddler "incident" never happened.
