When she's not running in her saucer, M likes to kick a ball with her feet. Between the running and the kicking it looks like her parents might be atteneding a few soccer games (football to her European fanbase).
Exercise is said to create an endorphin high, which M is displaying below. She also might be laughing because I just told her David Hasselhoff released seven albums that went platinum in Europe (better known as "The Hoff" to her European fanbase).
Many thanks to the McKinleys from M!
