 From 1786 until 1800, Sophie Piper served as "hovmästarinna" to duchess Charlotte.The friendship between Sophie and Charlotte somewhat cooled after Sophie had refused to accompany Charlotte on her trip to Germany in 1798-99 in favor of going there separately with her lover.This was followed by her resignation as the chief lady in waiting of Charlotte's court in 1800, after which Charlotte stopped writing her journal in the form of letters to Sophie.
