Game of Thrones episode 8 of season 4; why?

In episode 8 of season 4 we see Missandei in a stream I have several questions.
1) why was she doing laundry
2) why was she doing laundry nude
3) why was she doing laundry nude in a stream
4) why was she doing laundry nude in a stream outside the city
5) why was she doing laundry nude in a stream outside the city in company of a number of unsullied who were bathing in the stream outside of the city

any ideas.
