In the morning my duty in the St Stephan Church, from 10:ooam till 01:45pm. Pierre came over to the church to pick me up. Festivities in the city (and whole country!) because it was Kingsday, the birthday of HM Willem Alexander. He visited the city of Groningen, and there was also in the evening the Kings Concert. We had a stroll in the city and visited afterwards Erik and Ineke van Bronswijk.
