It's one of those stories where I feel there's more to it, but I just can't grasp it. Maybe there isn't. Some things I just don't understand, like one of the last sentences 'In the end we all prefer the bitter to the sweet,' while it's all about cookies which are sweet obviously. It's like it's all trying to tell you something, but I'm not sure what. But if others can't find a deeper meaning, perhaps there isn't one. Maybe the unending supply of cookies stands for the unending love of the mother for the boys, and in contrast to that is the brutal, loveless reality of the war. Something like that.
