And grandpa in a suit?

Bruno loves his grandpa very much. And now he is gone... Bruno's brother, Ksaver, claims that he is at the cemetery, while dad says - in heaven. But what is the truth here? Ksaver lies so much that Bruno doesn't know whether to believe him this time. And parents keep repeating: "You won't understand this yet"... At first, no matter what Bruno does, he feels a dull pain in his chest. As if he has a little hole in his chest under the sweater. But gradually it heals. Every evening before going to bed, Bruno looks at his grandpa's photo and talks to him. "I won't forget you," he promises his grandpa. And it seems that he smiles at him from afar.
