Status Updates From The Wee-Jees: A Ghost Story...

The events of the story are pretty spooky but the narration is not very good. Several aspects detract from the story, firts of all the fact that every kid that's not Craig acts and talks like an adults and second (and this is minor but it still bugged me), is he speaking in deutch or in english? Did he learn deutch before moving to Germany or is everyone in Germany using perfect american English to talk to him?
