My brother upset me and I have the urge to cut up his favorite toy.
What are you going to gain out of cutting up his toy?
I want to see how he will react.
That would be so mean. You should respect the belongings of others, especially when they are family.
Damn, I'm just playing.
I'm glad you are not serious, I'm just letting you know that you should respect his belongings. If you have these urges again just think of how you would feel if someone destroyed your belongings.
