A young family moved into a house next door to an empty plot. One day, a  gang of workers turned up to start building on the plot.
The young family's 5-year-old daughter naturally took an interest in all  the activity going on next door and started talking with the workers. She hung around and eventually the builders, all with hearts of gold,  more or less adopted the little girl as a sort of project mascot. They chatted with her, let her sit with them while they had tea and lunch  breaks, and gave her little jobs to do here and there to make her feel important.
They even gave the kid her very own hard hat and gloves, which thrilled  her immensely.
At the end of the first week, the smiling builders presented her with a  pay envelope - containing two pounds in 10p coins. The little girl took her 'pay' home to her mother who suggested that they take the money to the bank the next day to open a savings account.

At the bank, the female cashier was tickled pink listening to the little  girl telling her about her 'work' on the building site and the fact she had a 'pay packet'.
