We went out to play yesterday. The girls like to play catch with the soccer ball. I think that they choose the soccer ball over the basketball because they may want to kick the ball to each other.
After a while they decided that they were tired, but they still wanted to play. They got the chairs off of the front porch and sat in them, and continued to toss the ball back and forth to each other. I asked them if this still qualified as exercise, they just giggled.
