I took him into the backyard, and then, to my horror , Perky flew off. The enormous, blue sky swallowed up my sister’s blue  2   and suddenly he had gone, clipped wings and all.

When I was finally able to  12 , we examined the amazing evidence. The dates and the locations and the pictures of the bird all  13 . It seems our two families had been  14  long before we ever met. Forty years later, I ran to my sister and said, "You were  15 ! Perky lived!"
