It wasn't "they" who went to a children's home and fell in love with the two children. After Nora lost her unborn child, she went home and her husband was on his own in London. They both had kind of lost themselves, and the wife later said that she was not really her true self for a long time. At one point, during an air raid, Robert Young's character asks God to show him what to do. He did meet the little boy on the night his wife was injured, and later meets the boy, Peter, again in the home, where he also gets to know Margaret. His relationship with the two children seems natural, at times he gets frustrated, and the children aren't easy or angels, Margaret has been scarred by the war, and embarrasses him in front of other adults. Any parent, and parents of children who are dealing with difficulties, can relate to this, and it was nice to have this kind of realism shown in a 40's film. I've liked Robert Young in other movies, but wondered if this, in part, led him later to be cast as an iconic TV Father. I really liked this movie, it was moving, and gave you an idea of the things that adults and children went through during the London bombings; it did not whitewash the hardships, as some WWII films do. Right now, I'm thinking of my young child's fears and hard times just seeing (on TV) 911, and mistakenly thinking that it might have meant the loss of a family member...what we dealt with was nothing compared to Brits in the 30's and 40's. I'd never heard of this movie - definitely worth seeing.
