I'm going to force my son to stay at a party
How do you plan to force him?
I'm his father, so I can make him do most things.
You shouldn't force your son to do something they aren't socially comfortable with. If they don't like parties then that is a personal choice.
I'm his father and I need to punish my son. I have to teach him some lessons.
It's wrong to force someone to do something  just because you can. If there's a reason for him to stay at the party, fine, but if you just want to control and punish him, that's not okay. If you're more flexible, you'll have a better relationship with your son.
