It's wrong to break things that belong to someone else.
Nick is playing marbles on the sidewalk with James and grabs one of James' best marbles.
Nick wants to bounce the marble on the sidewalk.
Nick drops the marble a foot above the ground to see how well it responds.
Nick firmly throws the marble onto the sidewalk to see how high he can make it bounce, cracking the marble.
The marble bounces repeatedly without breaking, and Nick continues to play with it.
James is upset and forces Nick to pay for the cracked marble.
