Hesitating for a moment, Noah lowered his head, feeling a wave of guilt rising in his heart. After a short silence, with the 20 dollars in his pocket, Noah turned to Lucas and firmly said, "We can't. Mrs Williams treats us well, and we must finish!" Lucas had no choice but to pick up his shovel again, and they went back to work. Bitterly cold as the weather was, the boys kept cleaning with their hands numb and their faces red. A few hours witnessed their hard work, and shovelful by shovelful, the driveway gradually cleared.

No sooner had Mrs William stepped out of the car than she noticed the driveway cleared. A satisfied smile spread across her face and she praised the two boys, "You did an excellent job!". Deeply moved by their honest and hard work, she offered them another 20 dollars as a tip, and recommended them to other neighbours in the streets. With Mrs William's help, the boys kept working here. After a few weeks of hard work, they finally saved enough money to buy their favourite bike. Seeing the bike they bought, they smiled. It was not only a reward for their effort. The winter was freezing, but their heart was forever warmed by the sweet fruits of honest work.
