One day as I walked around the house with my sister Kathy's new parakeet （小鹦鹉）on my finger, I wanted to show Perky 1 the sky looked like. Maybe he could make a little bird 2 out there. I took him into the backyard, and then, to my 3 , Perky flew off. The enormous（巨大的）, blue sky swallowed up my sister's blue 4 and suddenly he had gone , clipped wings and all.

　　When I was finally able to 17 , we examined the amazing evidence（证据）. The dates and the locations and the pictures of the bird all 18 . It seems our two families had been 19 long before we ever met. Forty years later, I ran to my sister and said, "You were 20 ! Perky lived!"
