"Incident One" is about luck. It's about a girl who sees a cute puppy at school and decides that it's a good thing she has a cute dog. "Incident Two" is all about how lucky she is to be able to go outside and play in the rain and "Incident Three" is how unlucky she is when she accidentally drops her wallet on the way out the door. The girl is worried that she's been unlucky in the past, but she tells us that she doesn't think so.
