Carl Fredricksen was walking down the street. His new friends, Russell, the new Senior Explorer, and Dug, the talking dog, were with him. He came to a point in the city where they had to cross the street. When the "Stop" sign changed to "Walk," he started to cross, but he stumbled over the curb and almost fell.
"Mr. Fredricksen!" exclaimed Russell, rushing out to stop him from falling. Russell reached out and grabbed Carl's hand, saving him.
Dug trotted towards him. "Are you all right, master?" he asked.
Carl held his head for a second. "Yeah, don't worry about me, Dug," he replied, "I'm fine."
"Oh, good!" Dug said happily.
"Thank you, Russell," Carl said to the boy.
"No problem, Mr. Fredricksen," Russell said. "Just be more careful when stepping on or off the curb."
"I know how to cross the street, Russell," said Carl dryly, "I've done it for years. But thanks for your concern, anyway."
"Any time," said Russell.
Dug said, "We'd better hurry and cross the street while the 'Walk' sign is still on. We're holding up traffic a little."
"Good idea," said Carl, "Then let's get going."
