The Popy's Riddle

A beautiful women had been transformed by a witch into a poppy in a field. Each evening, she once again turned back to her normal self and was allowed to go home for the night. One morning, before the women went back to the field where she will turn into a popy again she told her husband that if you suceed in picking me then the spell will be broken. This was true, but her husband asked her how he would recognise her amongst all the other thousands of popy's? The answer is simple said the women. Because I spent the night at home I will be the only popy in the field that was not wet with dew!
