Tonight I arrived home at about 6:00 PM. My boys, Trent and Troy, ages 6 and 4, were ready for action. We started with a quick game of hide and seek and then outside for a jump on the trampoline. They love the trampoline. I remember one night arriving home from work and the boys were sitting quietly in the living room. Trent turned his head, and I saw the darkest bruise on his chin. “What happened?” He responded, “Mommy’s knee hit me in the chin.” I then saw Troy limping across the floor.
