context: We look out the window and discover it is a bright sunny day, which is perfect for going to the beach. We load up the car with all sorts of beach things: buckets, shovels, beach chairs, towels, and an umbrella. We also pack a lunch in the cooler. Everyone in the family puts on their swimsuits and sunscreen. We drive to the beach, and we all unload the car and walk to the beach. We set up on the beach, with our chairs and the umbrella. Mom reads her book in the chair and hangs out with the baby, while Dad takes the older kids swimming. They are very careful to not go in the water too deep. After a while, Mom goes swimming, and Dad builds sand castles with the kids. We eat lunch, and then we shower at the some of the showers near the parking lot. We load all the towels, and buckets, and shovels back into the car, and we drive home.
