On Saturday March 26th, I would like to celebrate my retirement as department head and my 60th birthday with you and your dearest person with a “Back to the 60s party”. We live in gruesome times when others have to flee their homes or country and endure atrocities of war. I have no material wishes, but if you want please donate generously to the United Assistance Fund (UAF) that helps (Ukranian) student refugees settle in the Netherlands
