My brother doesn't like to ride his own bike, so he hops on his sister's and rides it. My second brother has a habit of running behind anyone on a bike. So, that's how both of them get their exercise. It was around 7:00 in the evening when we all went outside to play. The sun was going down, and my two brothers were riding and running down the gravel driveway. It made for a cute, meaningful picture.
