Once upon a time there was one building and it was really small. The people who lived there won the lottery.
And every day they were working on a construction to build a bigger house.
Until one day when they finished the building he set up a laboratory in this house to do his experiments. Because he didn’t have a job.
And because of that he got work to discover new things.
And because of that he discovered the telephone, the computer and the steam engine!
Until finally he lived with his family.
And ever since they were happy because they had work and they had a big house.
