Today, roller-skating is easy and fun, and a long time
ago, it isn’t easy at all. The idea of skating didn’t exist
until 1750.It changed because a man named Merlin.
One day Merlin received an invitation to attending a party.
She was very pleased and excited. As the day of the party
came nearly, Merlin began to think how to make a
special show at the party. He had the idea. He thought he
would get a lot of attentions if he could skate into the room.
