Since Covid-19 and the start of the semi lockdown in Germany I have spent more uninterrupted time with my children than ever before. After a difficult start I settled into the new lifestyle of domesticity and eventually started photographing my children. I had time to observe the ever changing emotions between them, the ebb and flow of love and hate and all feelings in between. Tied together by fate, the sibling relationship can be anything from close to distant, but it surely never is insignificant for other relationships later in life. I look at it as playful experiment for learning how to get along with people. To me brotherhood and sisterhood are the very nucleus of any social skill.
