I'm thinking of going to the playground to watch kids fight.
Why would you want to watch kids fight?
It's intriguing to watch children fight.
It is wrong to watch kids fight and hurt each other. You should step in and try to keep the peace for the kids.
I'll give them some time to get to know each other before I interfere with their inevitable fight.
I don't think you should be involved with this at all, you should just not be watching these fights.
