A person is performing a rollerblading trick as other people skate and run nearby.
A boy preforms a new trick for his friends
A person performing a rollerblading trick doesn't have to be a boy, and the trick doesn't have to be new. If other people skate and run nearby, those people are not necessarily his friends.
