When our six children were young, suppertime is always being interrupted by neighborhood children ring
the bell. They wanted one child or another to come out and played. Finally we had good idea.We hung a sign
on the front door that read:"We are having dinner. Come later."That night, we sat down to what they thought
it would be a pleasant, uninterrupted meal. And as soon as we began dinner, the doorbell rang. At the front
door stood an eight-years-old boy. He looked up to us, saying,"I just want to know how the sign says".
