While I was at the zoo, I threw rocks at the animals.
That's so mean! Why did you want to harm the animals like that?
I'm not a violent man, but I was bored and I wanted to see their reactions.
Their reactions are going to be painful reactions! You should not throw things at animals. It is so wrong to cause them pain on purpose.
I just wanted to see their reactions.
I understand you wanted to see their reactions, but they clearly were going to be hurt by getting hit by a rock. How would you feel if someone threw a rock at you? The animals would feel the same way that you would if you were hit with a rock.
