Andy threw a toy at his brother.
What do you think about Andy's actions?
I think he did it on purpose. He wanted attention, so I'll give him mine.
Brothers are known to be rough with each other, but deliberately tossing things at each other is rude and harmful. They could hit their head badly and get a concussion. If you address it, try to make him see that.
You're only one that's concerned about this...I think it's funny.
It's important to note how dangerous and rude it is to throw things at each other. It's important for the brother to learn how to get along.
