Read the the passage from Anne Frank: A Diary of a Young Girl. Yesterday afternoon Margot and I were having a bath here and I said, "Supposing we were to take the children who are walking past, one by one, hoist them up with a fishing rod, give them each a bath, wash and mend their clothes, and then..." Margot interrupted me, "By  tomorrow they would look just as filthy and ragged as before."

"'Supposing we were to take the children who are walking past, one by one, hoist them up with a fishing rod...'"

"Yesterday afternoon Margot and I were having a bath here..."
