When Kyle walked into Paul’s Pet World, he looked very anxious. He walked quickly to the store owner, Paul. Paul jumped out of his seat to greet Kyle. He was the store’s first customer of the day.
“Good morning, sir!” Paul said. “What can I help you with?”
“Well, I…,” Kyle started to say.
“Wait, don’t tell me,” Paul stopped him. “You are looking for a…a new dog… for your daughter’s birthday. Right?”
“Not really, I just…”
Paul didn’t let him finish. “Ah, I’ve got it. You just opened a new business, and you want some fish for your office. I have some very nice goldfish over here.”
“Actually, I…” Kyle was starting to look very anxious. His face had a strange look on it.
“No fish? Ah, a cat! You look like a cat person. At Paul’s Pet World, we have the best cats. Take a look at this cat---- long, white hair. She is looking at you. She is thinking, “Take me home. Take me home.” Would you like some cat food and toys as well?”
l“No, thank you,” Kyle said. By this time, he had a pained look on his face. “Really, I’m no interested in cats or fish or dogs.”
“What do you want, then?” Paul asked.
Kyle looked like he was going to cry. “I just want to know if I can use your restroom!” he finally said.
