"When you go to the bathroom, always wash your hands."
Translation:Ke hele ʻoe i ka lua, e holoi i kou lima i nā manawa a pau.
Mahalo for the discussion! I would agree that it is optional in this case. If someone said to me "Ke hele i ka lua, e holoi i kou lima i nā manawa a pau," I would understand that they were talking to me, and that the "you" was implied. I've updated the sentence so that it should be accepted without the "ʻoe". Might take a little while to update.
Edit: since its not after the imperative it might actually not be optional :D this seems more like the "ke hiki 'oe ma laila" type of scenario where ive never seen it without the 'oe. Maybe for a sentence like "when you do something..." you need the 'oe. But again just trying to make sense of it and not actually knowing
i just got the last prompt wrong for removing slippers because it wanted me to state the action first and the "ke hele..." bit after. So I changed the order on this one to put the "ke hele..." bit second and now get this wrong too! This lesson is more frustrating than most as far as wanting extremely exact answers. We shouldnʻt have to memorize the answer to every prompt if the sentences are grammatically interchangeable.
I hesitate to accept these only because of the order. I would translate these two sentences as "Wash your hands every time you go to the bathroom" rather than "When you go to the bathroom, wash your hands every time" or "When you go to the bathroom, always wash your hands".
