     When Kyle walked into Ernie's Pet World, he looked very anxious. The shop owner, Ernie, jumped out

of his seat to greet Kyle. He was the shop's first customer of the day.

     "Good morning, sir!" Ernie said, "What can I help you with?" 

     "Well, I…" Kyle started to say.

      "Wait, don't tell me," Ernie stopped him. "You're looking for a …a little dog… for your daughter's

birthday, Right?"

      "Not really, I just …" 

      Ernie didn't let him finish. "Ah, I've got it. You just moved to a new office, and you want some fish for

it. I have some very nice fish bowls over here."

      "In fact, I…" Kyle was starting to look very nervous and strange.

      "No fish? Ah, a cat! You look like a cat person. At Ernie's Pet World, we have the best cats. Take a look

at this lovely one with long, white hair. She's looking at you. She's thinking, 'Take me home. Take me home.'

Would you like some cat food and toys, too?"

      "No, thank you," Kyle said. By this time, he was walking up and down. He had a terrible look on his face.

"Really, I'm not interested in cats or fish or little dogs."

      "What do you want, then?" Ernie asked.

       Kyle looked like he was going to cry. "I just want to know if I can use your toilet!" he said at last.
