Do faeries die?

"Do faeries die, Daddy?" "Well. I think they may live so long and have such interesting lives that in their end they just fade away." "Oh." She believes me. No doubt." But this question lingers. "Did my grandpas fade away?" This is serious. Grandpas have been a part of Sadie's dreams and questions for as long as she has been. They both died in their early 60s, victims of disease. Both, before she came into this world and our lives. I should be good at questions like this. Rowan had them when she was little, which seems like a forever ago now. "I don't think so Sadie. I think they left all at once, because they were tired."
