One year, my son’s two children came down from Seattle. Brooklyn was eleven and Jackie was eight. When they arrived, Brooklyn was especially clingy. She wanted to be hugged a lot and often a hug would last a minute or two. I knew the reason; she’d been away at a soccer camp the week before and her mom was with her just one night and then they came here for the week. Jack didn’t go to camp, so he had been with his mom and dad and wasn’t in the least clingy.
