I’m too busy!”The boy soon fell silent as tears fell from his big blue eyes. Feeling sorry, the father said:“You can finish later. The boy said nothing but quietly walked away.”That evening the father said:“Come and finish the kisses now, Andrew!”But the boy didn’t.Unfortunately, a few days later after the father’s birthday, the boy had an accident and died.
