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