@nerevars could you please tell me which 'Momo' story is referred to/who the author is? Also, do you know if/where 'The neverending story' is available online?
"Your mother-in-law wants to come over" should be "Your step-mother wants..." (mother-in-law would be her husband's mum, or at least a boyfriend's mum; step mother is the person that marries your father).
Thanks for translating the story!
