There are 5 sisters in a room: Ann is reading a book, Margaret is cooking, Kate is playing chess, Marie is doing the laundry. What is the fifth sister doing?

They come to witness the night without being called, a sailor's guide and a poet's tears. They are lost to the sight each day without the hand of a thief.
