Sounds of eating. Crunching, chewing, swallowing. In this case the enjoyment of the eating is made into sound. You might wonder what is the waiting in that. Well one it is the waiting of the food to go down but it is also the waiting of the parent of the child, waiting for her to finish. This is an integral part of waiting. While one waits things are happening. And in this case a good thing. A child enjoying her food.
