"오후에 집에 가요."
Translation:Let's go home in the afternoon.
In speech Korean, we rely on verb endings and intonations to distinguish the sentence type whether it is declarative, interrogative, propositive, imperative or exclamative.
But in order to distinguish them in writing especially when verb endings of different types look similar like in this case, proper punctuation marks should be used.
So for the sentence above to be "propositive", may be an exclamation mark (!) is needed?
오후에 집에 가요. I go home in the afternoon
오후에 집에 가요! Let's go home in the afternoon!
