Mark’s brother, Jamie, rang Mrs. Grady’s doorbell. “You know her better than I do, Mark. You do the talking.”

“Hi, Mrs. Grady,” said Mark when their neighbour opened her door. “Would you like us to shovel（铲雪）your sidewalk and driveway?”

Shoveling was Jamie’s idea, a way to make enough money for the new Ocean Kingdom video game that came out the next day.

Mrs. Grady touched her hand to her heart. “That would be wonderful, boys. I think the job is getting to be too much for me.”

“It will cost 10 dollars,” Jamie said.

“If that’s OK,” Mark added.

“Oh dear,” Mrs. Grady sounded disappointed (失望的). “I haven’t been able to get to the bank. I can offer homemade cookies, but I realize that’s not what you had in mind.”

Mark was going to say that Mrs. Grady could pay them another time, but Jamie cut him off. “We’ll come back later.”

As they walked back, Mark looked quickly over his shoulder. Mrs. Grady stood at her window, watching them.

She didn’t look like the person who came to make him safe last summer when Mr. Dunn’s collie（牧羊犬）, Goldie, get away from her backyard. Goldie had just wanted to play, but Mark didn’t feel comfortable around big dogs. And Goldie had boxed him in between the wooden fence（栅栏）and the cedar hedge (雪松树篱).

Mark had tried to call for his dad, but his tongue (舌头) seemed locked behind his teeth.

Then Mrs. Grady’s front door had flown open. “Hold on, Mark. I’m coming!” She picked up a broom. “Goldie!” She’d called. As soon as Goldie had turned her head, Mrs. Grady had appeared quickly between Mark and the dog.

“Goldie, go home!” Then she’d swept her broom to hurry the dog along.

When Mark’s father had appeared, he’d said to Mrs. Grady, “That was very brave! Thank you.”

Mrs. Grady had laughed. “It was nothing. Good neighbours watch out for each other, don’t they?”

And now Mrs. Grady needed Mark as much as he’d needed her last summer.

He smiled and then dug deep into the snow.

“Hey!” Jamie shouted. “What are you doing?”

Mark couldn’t explain about Goldie and watching out for neighbours. “I like Mrs. Grady’s cookies,” he said and continued.

“It’ll take you all day,” his brother complained. “We’ll never get that game.”

Mark kept digging. Surprisingly, Jamie joined in.

Mark smiled. Jamie had known all along it was the right thing to do.

“Once the other neighbours see the good job we’ve done, they’ll line up to hire us,” said Jamie. “We’ll make money soon enough.” As usual, he had it all worked out.
