A Riddling Tale
Jacob and Wilhelm Grimm
Three women were transformed into flowers which stood in a field. However, one of them was allowed to be in her own house at night. One time when day was approaching, and she would have to go back to her companions in the field and become a flower again, she said to her husband, “If you will come this morning and pick me, I shall be set free and stay with you from then on.”
And that is what happened.
Now the question is, how did her husband recognize her, for the flowers were exactly alike, and without any difference?
Answer: While she was in her house during the night and not in the field, the dew did not fall on her as it did on the other two, and by this her husband recognized her.
