In our home we have a large family. So, over the years, we have created a tradition of ringing a bell when it is time for the evening meal. Once the bell is rung, children come from all directions, salivating at the prospect of food. If we have visitors, there is often some surprise at the sound of a bell being rung and even more surprise when children appear instantaneously at the meal table, seated with cutlery in hands and ready to eat.
