It shows a middle-aged man attempting to learn how to skateboard - he is watching You Tube tutorials in work and spending all his free time practicing and falling off - despite the fact his back is so sore, he can barely put the star on the top of the Christmas tree.
Turns out he is practicing how to skateboard for a reason. The doorbell rings and himself and his wife are met by a social worker and a teenage girl (and her skateboard) they are fostering.
