He liked to make things and play the violin in his free time. Joseph Merlin was a man of ideas and dreams. People called him a dreamer. One day Merlin was invited to a party. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make an amazing entrance at the party. He had an idea. He thought everyone at the party would show much interest if he could skate into the room. Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was proud of his invention and dreamed of arrived at the party on wheels while playing the violin. On the night of the party Merlin rolled into the room playing his violin. Everyone was surprised to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. The mirror fell down, breaking into pieces.
