"To be sure!" said Seseley, with sympathy. "I never thought of fairy life in that way before. It must get to be quite tiresome." "And think of the centuries I must yet live!" exclaimed the fairy in a dismal voice. "Isn't it an awful thing to look forward to?" "It is, indeed," agreed Seseley. "I'd be glad to exchange lives with you," said Helda, looking at the fairy with intense admiration. "But you can't do that," answered the little creature quickly. "Mortals can't become fairies, you know--although I believe there was once a mortal who was made immortal."
