What do you think about my plan to go scare some girls in the park?
I think that sounds mean. Why do you want to scare them?
I'm bored.
You shouldn't mess with people because you are bored. Scaring people is rude and dangerous. Instead, find something to do to pass the time that doesn't upset other people.
I've decided not to do it.
I'm glad to hear you changed your mind! You are making a good decision by choosing not to scare them.
