The best example of this is our own helpers, who have managed to pull us through so far and will hopefully bring us safely to shore, because otherwise they'll find themselves sharing the fate of those they're trying to protect. Never have they uttered a single word about the burden we must be, never have they complained that we're too much trouble. They come upstairs every day and talk to the men about business and politics, to the women about food and wartime difficulties and to the children about books and newspapers. They put on their most cheerful expressions, bring flowers and gifts for birthdays and holidays and are always ready to do what they can. That's something we should never forget; while others display their heroism in battle or against the Germans, our helpers prove theirs every day by their good spirits and affection.
