We take the kids to the park and give them the full service experience: spot them on the climbing frame; purchase mini muffins with sticks; push the swings; and kick and throw balls. Mark and Greg get in a few passes with the frisbees before Oscar takes over. In the background, two 50-something couples indulge in a relaxed game of mixed doubles. I note I'm not the only one glancing wistfully in their direction.
