Blackbird (1970)

Motte is 15 years old in the fall of 1977 and has to come to terms with the news that his best friend Bogi has to go to the hospital with a life-threatening illness. This is a seemingly impossible task, because his first love, his parents' impending divorce, his enthusiasm for Bowie and soccer, an omnipresent chimney sweep, and his anger at not being able to share all this with Bogi overwhelm Motte and lead him to make himself scarce at the hospital.
