They were the only ones who seemed to be having a good time in spite of the situation. Sitting on the floor, they reached into a small carry-on bag, pulled out a handful of plastic Mutant Ninja Turtles, and proceeded to enjoy themselves. When they tired of this, they traced the lines of the carpet with their feet. They repeatedly counted the number of colors in each section of the rug. And they made up a game by hopping from one pattern to another.
Kids can amuse themselves with almost anything.
I remember my mother telling me that when I was very young, we would sometimes visit a distant aunt. I would immediately go into the kitchen, take out all the pots and pans from the cabinet and proceed to play with them for hours. The lesson adults can learn here is that the world is filled with things for our enjoyment. The trick is to open our eyes and look for them. They can find a penny on the sidewalk and feel rich.
