explain the meaning of the following lines:-
"it looks as though captain von stahle preffered to stay with you tonight,stjernstrom",he said to the master blacksmith, and turned on his heel.
but he laughed to himself as he went away, and the blacksmith, who knew him, understood very well that he had not said his last word.
the ironmaster wants to send his oldest daughter to convince the captain and stay tonight with them as he was the old aquaintance of the iron master and help them to make christmas food and that's why ironmaster laughed to himself and went away
the master blacksmith understood him very well
