     Ever since we became pen pals, Julien has sent me strange things. Once, she sent her sneeze in a jar. ("I
have a cold, can you tell?" she wrote. ) Then she sent her fingerprint. ( "So you'll recognize me in a crowd.")
     Julien sent me breakfast, all right: cornflakes. Soggy, milky, grainy, crumbly, limp cornflakes scraped from
the bottom of her cereal bowl. I lost my appetite, but I read the letter.
Dear Caitlin,
     These cornflakes were so nutritious that, wanted to share this high-fiber, low-sodium,
 just-three-calories, balanced breakfast with you.
       Enjoy,
      Julien
      P. S. Next week I'm sending you a sunset,
      "She's mistaken," I told my mom. " No one can send a sunset, not even Julien. It's impossible."
      "I don't know," Mom said."Julien might find a way. After all, she did send you her sneeze.
     A week later I checked the mail and found a box with air holes and the words "FRAGILE-THIS SIDE UP"
printed in bold black letters on the top. It was from Julien.
     I stroked the box with my fingers. It was perfectly dry. I smelled it. It didn't smell. I held my breath and
started opening the package. What if sunbeams spring out and hit me in the face like those fake snakes in a
can; I thought?
     My hands shook as I lifted the last flap and peeked inside. Where in the world was the sunset? All I could
find was a letter and a twisty, gray, papery shell. It looked like a submarine. I read the letter.
Dear Caitlin,
     The sunsets at my house are so beautiful that I had to give you a piece. I counted at least
five different colors in one yesterday. Can you find more?
    Hugs and smoochies,
    Julien
     I looked again at the gray shell. That's no sunset, I thought. "You must mean the submarines at your house,
Julien," I said. Without reading the postscript, I laid the letter and the submarine on the kitchen table. Then I
left the room to find a pen so that I could cross out "sun-set" and write "submarine" above it.
     When I returned, I stared in shock at the submarine. A creature was oozing out of it! Was it a sea monster?
I looked closer. It was a winged creature... an insect... a butterfly. An orange, blue, purple, red, and gold
butterfly. It looked like... a sunset!
     While the sunset opened and closed its wings to dry them, I read Julien's postscript. It said, "P. S. Next
week I'm sending you Japan."
