Roger Dee Just a one-eyed dog named Charlie and a crippled boy named and named it Dugan, and after that he never said anything more about When school opened again in the fall Ethel sold her trailer and got a going to Michigan to find Charlie. It was only natural, of course, because kids—normal kids—forget their pain quickly. It's a sort of When they were gone the Twin Palms trailer court was so lonesome and country for the sugar cane season. We never heard from Ethel and Joey dead that Doc and I pulled out and went down to the Lake Okechobee He said, "No, Roy," without taking his eyes off the sky. For a minute I had the prickly feeling you get when you are watching a not especially interested now in where Ethel and Joey Pond are or how I wish I'd asked Joey or Ethel, before they moved away, how Charlie Probably I'd have asked who Charlie was but just then the trailer door accents every day. "Let the boy alone." She was right about it being none of my business. I went on into the trailer I shared with Doc Shull and left the two of them waiting for Doc got up and stepped into his pants. He padded barefoot across the linoleum and poked at the packages on the sink cabinet. "Snapper steak again," he complained. "Roy, I'm sick of fish!" "You don't catch sirloins with a hand-line," I told him. And because I'd never been able to stay sore at him for long I added, "But we got bathroom this afternoon while his mother was away at work, and my selflessness had its just reward." uncle, and he's keen enough to read my mind like a racing form.

He hadn't touched her bottle though his insides fishing and migratory crop work, because he's used that charm too often in the wrong places. "Good enough," I said and punctured a can of beer apiece for us while Ponds were permanent residents. The kid—his name was Joey and he was ten—was a polio case who hadn't walked for over a year, and his mother was a waitress at a roadside joint named the Sea Shell Diner. There wasn't any Mr. Pond. I guessed there never had been, which would explain why Ethel acted so tough and sullen. We were halfway through supper when I remembered something the kid had year ?" Doc nodded, seemed to lose interest in the Ponds, so I let the subject drop. We sat around after supper and polished off the rest of the beer. When we turned in around midnight I figured we wouldn't be nearly always a jackpot—from a pool made up at the beginning of every run—for the man landing the biggest fish of the day. There's a knack to hooking the big ones, and when the jackpots were running good I only worked a day or so a week and spent the rest of the time lying around the trailer playing cribbage and drinking beer with Doc Shull. Usually it was the life of Riley, but somehow it wasn't enough in this place. We'd get about half-oiled and work up a promising argument looking its screwball funniest with our arguments one or the other of us would look out the window and see Joey Pond in his wheelchair, waiting for a one-eyed dog named Charlie to come trotting home across the palmetto flats. He was always there, day or night, until his mother came home from work and rolled him inside. Ethel Pond told me quick to mind my own business. Doc explained that the kid didn't want another mutt because he had what Doc called a psychological block. with Joey than Ethel had, and the kid felt as safe with him as he'd had depended on Joey for the affection he wouldn't take from anybody At first I thought it was funny that Joey never complained or cried when Charlie didn't come home, but Doc explained that it was all a admitting that Charlie was lost. So he waited and watched, secure in his belief that Charlie would return. The Ponds got used to Doc and me being around, but they never got what you'd call intimate. Joey would laugh at some of the droll things Doc said, but his eyes always went back to the palmetto flats and the his routine. That routine started every morning when old man Cloehessey, the postman, pedaled his bicycle out from Twin Palms to leave a handful of mail for the trailer-court tenants. Cloehessey would always make it a point to ride back by way of the Pond trailer and Joey would stop him and ask if he's seen anything of a one-eyed dog on his route that day. fellow had two eyes on him. 'Twasn't Charlie." Then he'd pedal away, shaking his head. Later on the handyman would come around to swap sanitary tanks under the trailers and Joey would It was hard on Ethel. Sometimes the kid would dream at night that Charlie had come home and was scratching at the trailer ramp to be let in, and he'd wake Ethel and beg her to go out and see. When that happened Doc and I could hear Ethel talking to him, low and steady, until all hours of the morning, and when he finally went back to sleep we'd hear her open the cupboard and take out the gin bottle. Pond and Doc and me. Doc and I were turning in around midnight that night when the kid sang out next door. We heard Ethel get up and go to him, and we got up too and opened a beer because we knew neither of us would sleep any more till she got Joey quiet again. But this night was different. Ethel hadn't talked to the kid long when he yelled, "Charlie! Charlie! " A little later Ethel came out into the moonlight and shut the trailer I knew what he meant and wished I didn't. Ethel had finally told the That's why I was worried about Joey when I came home the next evening "Books for Joey," Doc said. "Ethel and I agreed this morning that the He went on to explain that Ethel hadn't had the heart the night stars ?" Doc said when I told him. "Good Lord, Roy—" Ethel Pond knocked just then, interrupting him. She came in and had a the sky like that he'd say only that he wants something to remember Charlie by. It was about nine o'clock, when Ethel went home to cook supper. Doc across the sky in a curving, blue-white streak of fire. I didn't pay much attention, but Doc nearly choked on his beer. "Roy," he said, "that was Sirius! It moved! beer ?" I asked. Doc laughed at that, sounding more like his old self. "No, Roy. No because it wasn't bright enough to suit Joey's taste, but Doc called "Don't joke about Joey," he said sternly. "Getting back to Pond trailer, a boost up the entrance ramp. I pushed him inside where Doc couldn't hear, then I asked him how things were going. "Slow, Roy," he said. "I've got 'most a hundred to go, yet." "Roy," he said, without taking his eyes off his toes, "did you know that Doc is an awfully wise man?" I said I'd always thought so, but why? finished because Joey Pond lost interest in it when he learned to walk wheelchair again. Ethel sent him to school at Sarasota by bus and before summer vacation time came around he was playing softball and fishing in the Gulf with a gang of other kids on Sundays.
