Can I ride?

When I found out that I was pregnant with Charlie, I worried about the age difference. Would Jack be a good helper? Would he want to play with his brother? Would he be loving and gentle? I have no idea why I worried. Jack has the sweetest soul. Just look at him push his brother on the swing and then give him a ride in his beloved Jeep. Notice how his makes sure he puts on Charlie's seatbelt because(in his words), "that's what people do when they love you."
