"You cannot neither go to school nor home"
Translation:Huwezi kwenda wala shuleni wala nyumbani
That's not what the sentence is saying I believe. I think it's saying "you can't not go to school and not go home" i.e. " You have to either go to school or home you can't go elsewhere". English is fine with double negatives in spoken English, it's just awkward to read written.
