Matti and his grandfather have always understood each other well. Now the grandfather is very old and sick. His family and friends have gathered around his bed, knowing that he will die, and they are crying. Only Matti does not cry; instead, he observes a fly. He has his own way of dealing with grief and death: he remembers the many walks with his grandfather and everything he explained to him. For example, why flies can crawl on the ceiling. One of the most beautiful stories about saying goodbye and the certainty that we do not lose anyone we keep in our memories.
