Because that was really nice of them to go through all that trouble .Because they were hungry .Because they came back to the house to see the progress .None of the above choices .
Why did they have dinner ?
I thought that was really nice of them to go through all that trouble to put all the information together for us . It was really sweet . After dinner they came back to the house to see the progress . It was the first time they had been there since construction started , so they had a lot to see .
